Callback error - main branch

[d-sel]

I'm encountering errors when I click on Section-2 tab. Can others please see if they can reproduce the error and, if so, can you please check latest pushes to main?

That's Interesting! I assume this error is without making any changes to the main if not please correct me. I re-ran from the main branch but am not able to reproduce the error on my laptop. Maybe others can have a look and see as well to check.

[d-sel]

Yes, this is from main without any changes.

[chiragrank]

Thanks for confirming that. Maybe @mikelynch416 and @fatse can have a look to see if they are able to reproduce the error so that we can investigate further

[mikelynch416]

Yeah I'm seeing the same error as well now that I click on the third tab. My bad for merging the pr without noticing that error

Edit: While trying to figure out the cause I restarted it locally and the error is not appearing for me anymore?? Also it doesn't seem to happen on Heroku

[chiragrank]

@d-sel Does restarting solve the issue for you?

[d-sel]

By restarting, you mean stopping the server and running again? If so, no, it does not solve the issue.

I am running it locally (not on Heroku).

[chiragrank]

Yes, I meant starting it locally again.

[d-sel]

Intermediate fix: refresh browser window will stop the error from showing up. However, if restarting the app locally, will prompt the error again.

Will see if this shows up in Heroku. Otherwise, can leave for later as doesn't impact functioning of app.

[fatse]

We can close this Issue as you @d-sel and @chiragrank brought this up to the instructor and the cause of this issue still remains unclear and unhandled. As Joel suggested, it's probably a machine-related bug.
