QUESTION
I have this code to hash an object.
I am saving this hash as a key in redis with a timeout but even if I change something in that incoming request object it is generating the same hash and redis shows there is same key already there.
Does this package have some trouble on hashing or does my code have any problem?
...ANSWER
Answered 2022-Feb-15 at 10:02You can't pass an Object to the SHA256 Method, you may only pass strings and WordArrays.
When you pass an object, cryptojs will run .toString()
on it, which will always give the same output ([object Object]
), and thus the same hash.

I am trying to create a blogsite to which I have set up my authentication using auth0 and express as my backend. For the client side I am using react. To know about the info about the logged in user I need to send req.oidc.fetchUserInfo()
object via the API.
By some research I have gotten to this point:
...ANSWER
Answered 2021-Jul-11 at 09:24You need to specify what scopes (like "openid email profile...") you want to have access to and in your code I don't see that. If you don't ask for any access, then you won't get any access tokens.

QUESTION
I need to upload a v8 heap dump into an AWS S3 bucket after it's generated however the file that is uploaded is either 0KB or 256KB. The file on the server is over 70MB in size so it appears that the request isn't waiting until the heap dump isn't completely flushed to disk. I'm guessing the readable stream that is getting piped into fs.createWriteStream
is happening in an async manner and the await
with the call to the function isn't actually waiting. I'm using the v3 version of the AWS NodeJS SDK. What am I doing incorrectly?

...ANSWER
Answered 2021-Jun-14 at 03:53Your guess is correct. The createHeapSnapshot()
returns a promise, but that promise has NO connection at all to when the stream is done. Therefore, when the caller uses await
on that promise, the promise is resolved long before the stream is actually done. async
functions have no magic in them to somehow know when a non-promisified asynchronous operation like .pipe()
is done. So, your async
function returns a promise that has no connection at all to the stream functions.
Since streams don't have very much native support for promises, you can manually promisify the completion and errors of the streams:
