ANSWER
Answered 2021-Feb-27 at 08:20Your issue is because when data
is initialised in the useState()
call, it is undefined, if you were to run handleNameSearch
immediately you'll find that it would crash because data
is undefined, as your flow error says, so then data.students
would crash, and flow is throwing an error to prevent this.
There are a number of ways to prevent this, either you return null
early above the creation of your handleNameSearch
function though this is probably wrong given what you're trying to accomplish as a filter.
I doubt the rest of your logic would function properly if we simply ignore this error though so to get you by, I would suggest you just do the simplest thing and only run the code block if data is populated

After having updated my flow-bin package from 0.142.0 to 0.143.1, I got hundreds of error messages like this one (signature-verification-failure):
I know this version of flow made types-first the default mode but still, I don't understand since all of my functions are properly annotated, like in this simple class:

I recently updated a project using Flow to version 0.138.0. After the update, it's the first time I'm stumbling upon similar errors like this:

QUESTION
On our application we are using flow for typechecking, which is all good and fine, however there seems to be a very large amount of dependencies that need to be checked on each incremental pass of the type checker, a single change on a very leaf component generates the following output:
...ANSWER
Answered 2020-Nov-28 at 02:55You should try upgrading Flow to v0.133 and switch to the Types-First architecture, or enable it on earlier releases. The rechecks have considerably improved, as explained, since all module exports are now annotated instead of being infered. There is a codemod availble for annotating exports on large codebases:
QUESTION
I'm trying to implement safari notifications and I have most things figure out. I'm following the official tutorial https://developer.apple.com/library/archive/documentation/NetworkingInternet/Conceptual/NotificationProgrammingGuideForWebsites/PushNotifications/PushNotifications.html#//apple_ref/doc/uid/TP40013225-CH3-SW1 but I'm currently receiving the error:
Extracting push notification package failed
I have seen this topic APNs "Extracting push notification package failed" but it seems the person didn't get any feedback / solution.
Before this error, I was getting "Signature verification of push package failed." but I endup solving the issue with this help Apple website push: Signature verification of push package failed, but apple certificates are ok and by downloading/converting to PEM the latest Apple certificate https://www.apple.com/certificateauthority/AppleWWDRCAG3.cer
Website.json has the following data:
...ANSWER
Answered 2020-Nov-27 at 17:43Solved.
I had several things wrong in my code.
- The error:
Extracting push notification package failed
Was caused due to an echo ...
in the middle of the code when creating the zip file.
- The error:
Signature verification of push package failed
Was caused due to several factors:
- My .p12 certificate was wrong, the .p12
Website Push ID
did not match mywebsite.json
nor the javascript code. In order to debug / view the data of the certificate I used the commandopenssl -nokeys -info -in certificate.p12 -passin pass:
- The certificate AppleWWDRCAG3.cer (that expires in 2030) from the oficial link https://developer.apple.com/support/expiration/ doesn't work. I had to download the file AppleWWDRCA.cer (that expires in 2023) from https://developer.apple.com/certificationauthority/AppleWWDRCA.cer
- My icons were not created in 72dpi resolution
- The version used by the Safari to request permissions is the version 1 "v1/pushPackages.." and I was creating the zip file with the
manifest.json
in the version 2

ANSWER
Answered 2020-Sep-23 at 12:46I assume you're on the latest version of flow, 0.134.0 which is the first version with types-first enabled by default.

QUESTION
Followed by Managing commit signature verification guide, I've created GPG key, added it to my GitHub account and have set my git to using it when signing commits. So now I can do signed commit from terminal like so:
git commit -S -m "Comment was added. Commit from console."
, and push changes to the GitHub.
But how can I sign in commits with same GPG in Atom? Now after staging - committing - pushing it's not verified:
Cannot find info about it in the manual: GitHub package
...ANSWER
Answered 2019-Jun-06 at 02:51Some Git integrations support commit signing, and some don't. It doesn't appear that Atom supports controlling whether commits are signed. However, Git does provide an option to sign all commits which you can use.
If you want to sign all your commits, you can set the configuration option commit.gpgsign
to true
, and that will cause all commits to be signed unless you provide the --no-gpg-sign
option. That should also be true of any commits created in Atom or other tools.
If you want to do it only for this repository, simply edit the .git/config
file or use a plain git config commit.gpgsign true
; if you want to do it for all commits, regardless of repository, you can edit the .gitconfig
file in your home directory or use the --global
option in that git config
invocation.
QUESTION
I installed Git on my Mac and then tried to set up GPG signature verification by following the steps outlined in Github.
The first time I did a test git commit
through the Mac OS Terminal I was requested my passphrase and the commit was properly signed and pushed through. No problems.
Then I tested the signature verification through the Atom editor. This time, however, the git commit
signing failed.
I tried looking for solutions on Stack Overflow and GitHub but was unable to find any that worked although I did try some of the suggestions proposed.
Unfortunately, now when trying to git commit
via the Terminal, I get the following error message:
error: cannot run --version: No such file or directory
error: gpg failed to sign the data
fatal: failed to write commit object
I have spent a few days trying to find a solution online but have not been successful.
I do not understand the first line of the error message ( cannot run --version: no such file or directory ) and have not been able to find a similar issue online.
Further attempts and trials at finding a SolutionOver the last couple of days I have tried a lot of things based on suggestions from the following sites:
- gpg failed to sign the data fatal: failed to write commit object
- Git Hub Desktop on Mac, error: cannot run gpg: No such file or directory
- Automatic Git commit signing with GPG on OSX
- How to set up git to use the GPG Suite
I have also done the following:
- Tested GPG signing through GitKraken which works without any issues.
- Tested with GitHub Desktop and got the following error:
Error: Commit failed - exit code 128 received, with output:
'error: gpg failed to sign the data fatal: failed to write commit object' - Tested with Atom editor and got the following error:
Unable to commit. Error: gpg failed to sign the data fatal: failed to write commit object
- Uninstalled GnuPG and reinstalled through Homebrew.
- In the end I even tried installing GPGTools' GPGSuite.
Unfortunately the problem persists and I no longer know what to try.
The output that I got for git config -l | grep -E 'gpg|sign
is:
user.signingkey=00C23E4C0619F0BD
commit.gpgsign=true
gpg.program=/usr/local/MacGPG2/bin/gpg2
I could do the following:
git config --global commit.gpgsign false
But this would not resolve the issue and I would still not be able to sign my git commit
.
What confuses and frustrates me is that it worked during my first git commit
after setting everything up following the steps outlined in Github's official guidelines. I am not sure what I did since then so that it no longer works. I have tried to back track and erase any changes but so far I have still not been able to resolve this issue.
Any help and guidance would be greatly appreciated. Thank you!
Update 1Out of curiosity I tried doing a git commit
through Terminal with a different local repo. The commit went through without a glitch and when I checked on Github it was signed and verified. I did further tests to commit and sign via GitHub Desktop and Atom, everything works fine without any issues. This is good news and gives me hope. However, I still have no idea why git commit
works on one repo and not on the other repo I was testing with. The original repo I was testing with still cannot git commit
and gives the same error message that I detailed above... I wonder what is wrong?
I am running the following:
- macOS 10.14.4
- git 2.21.0
- gpg (GnuPG) 2.2.15
ANSWER
Answered 2019-May-08 at 06:50After testing, since the issue seems to be only on one of my local git repos and not on any other local git repos, I concluded that overall, Git, GitHub Desktop, Atom, and GPG Signing are all working fine and the issue is specific to that one local git repo.
Although I have tried my best and still not found out exactly what is wrong with the buggy git repo and because I don't seem to be getting any additional leads/solutions from Stack Overflow I decided to do the following:
- Delete my local git repo that had the issue.
- Reclone from the remote repo.
- After a successful
git clone
redo tests withgit commit
and GPG signing via the Terminal, GitHub Desktop, and Atom. - All are now working fine.
I guess I might never know what really happened but I am glad to confirm that at least everything is working again normally. Thank you @bk2204
