With selectedItemColor:_selectedIndex == 0 ? Colors.cyan: Colors.grey, you tell Dart to assign the Value Colors.cyan or Colors.grey to the named argument selectedItemColor. However the _selectedIndex == 1 ? Colors.cyan: Colors.grey is misplaced there.

QUESTION

The Lambda function associated with the CloudFront distribution is invalid or doesn't have the required permissions

Asked 2021-Mar-19 at 08:46

So as a pretext, I've got less than no idea what to do about this. I've researched for about two hours and normally I would just keep going but none of the information I've found has been useful. I suspect this would have something to do with the YAML (serverless.yml) file but I am unsure. I've made several updates to the file so I will post the initial code and the current code though no difference has been made. The code worked flawlessly in development but throws errors in production. You can see https://www.evote.space to replicate this.

So after careful research I did the following and this is apparently a pretty common issue so I recommend anyone else suffering from this issue do exactly the following. Please remember this is with the serverless-nextjs component not just the serverless framework although the same may apply there:

I carefully dug through the repository README and followed all instructions.
I logged into the AWS Console and found what I thought was the primary issue but was actually a tertiary problem; The Lambda@Edge was only configured with basic CloudWatch Logging permissions. I updated it with all of the necessary privileges while ensuring best practices
After updating your Lambda make sure you deploy it to Lambda@Edge (Under Actions Menu)
Then I navigated to CloudWatch and checked the logs in the correct region and found errors after calling into the API.
Somehow my DynamoDB tables got deleted or weren't properly replicated so I redeployed them from my SDK with npm run infra and after.

This experience is always a good one to have. Your by no means invincible to really stupid errors in your code. And 99% of the time if you're stuck and thinking it's complex and that it's unrealistic that you'll fix it, step back and ask, "What's the dumbest thing it could be?"

And it's always that.

QUESTION

Detecting duplicates in a number (Python)

Asked 2021-Mar-07 at 16:33

I am currently working on a small project that involves analysing ballot papers and determining the winning candidate based on the number of votes they receive. The voting system is unusual. For example, if there are four candidates the vote could look like this: 2341 (2 for the first candidate, 3 for the second candidate etc.). However, if the vote looks like this: 2334 it is invalid, the same number cannot be used twice in the vote. I was wondering if there is a way to check for duplicate numbers within a number. I already have a solution, however it does not work for all of my test cases.

Asked 2021-Feb-12 at 01:34

I am having trouble writing my json data to a google sheet - I get the exception "The number of rows in the data does not match the number of rows in the range."

I think the problem is with how the range is set - but I don't know how to fix it. I include a sample of the json data after this script:

ANSWER

Answered 2021-Feb-12 at 01:34

Issue:

Apparently you can't get a range with 0 rows. In this method getRange(row, column, numRows, numColumns), every parameter should be a number larger than 0.

Why is rows.length 0?

The issue has to do with the fact that your JSON dataSet is not an array, therefore the for loop is terminated because dataSet.length is undefined. As a result row.length is zero because no values were added.

Updated Solution:

Assuming the first row (headers) in your sheet is:

QUESTION

Sheet embedded function -only works for spreadsheet owner, not "anyone"

Asked 2021-Jan-27 at 08:37

Long time learner/lurker, first time poster:

Howdy folks-

I've deployed a web-app that runs as the user (not me). It creates a form and a linked-spreadsheet in the users drive with "anyone" access and "edit" permissions.
Bound to this spreadsheet is an installable "onOpen" trigger that creates a UI menu item to the right of the spreadsheet's "help" menu, and on that menu item is a function that manipulates the data in the spreadsheet. That all works properly -for the user who created the form+spreadsheet.

Here's my problem: The use-case for my web-app is to allow someone to create the form and spreadsheet then hand it off to someone to use the form and view responses and tally votes via the spreadsheet.

Because the spreadsheet's access is "anyone", the person to whom the spreadsheet is handed-off can EDIT the spreadsheet, but the "onOpen" trigger never fires unless and until the opening-user signs in.

Then, the next problem: Assuming the handed-off person signs in and sees the new UI menu item, they cannot successfully RUN the function on the menu. It appears only the user that originally created the form+spreadsheet is the one who can run the funtion from the UI (addMenu) menu.

Questions:

what's the best/recommended way to detect a user is not signed-in ..so I can present a modal alert when the spreadsheet is first opened? The goal is to alert the user that if they signed-in, they would see the menu item by activating the installable trigger.
Can a modal alert be presented when a user is not signed-in? I'm not sure how that code would be triggered too, as it's likely the same problem as not triggering the onOpen UI-addMenu code
what's the best/recommended way to set the permissions for the spreadsheet's (embedded) menu-function -so the user opening the spreadsheet can run it vs. only the original creator of the spreadsheet.

web-app example: https://forms.fattm.org/contest-form-creator (several forms can be created, but the problem described above relates only to the form named: CONTEST BALLOT (Item 1179) ..so you can un-check the others before hitting submit)

Thanks for your time/thoughts/help!

Answered 2021-Jan-27 at 08:37

Welcome to SO!. The script you have that creates a custom menu using onOpen is a container-bound one, bound to the spreadsheet you are sharing. However the onOpen function is a trigger function which must be installed first (for each user that wants to use it) There is no way to get around this, unless you publish an add on, in which case the users would still have to install the add on the sheet you are providing.

You're writing to a file, then opening the file again and without flushing your first write either explicitly, or by closing the file handle, you're reading a file. The result is you're reading the file before you finish writing it.
