New Web app deploy broke CORS

[Timothy Hanson]

I have a Web app I have used for years.  It creates an updatable JSON file that is accessed via a URL.

I did a small code update to it and redeployed it as a new Web app but now the CORS is broken and I cannot access the data in a different web aplicaction via the URL

Is there a built-in solution to this?  when deploying the web app in google? (did not see anything)

and nothing in the code that has `COS` in it

Any ideas?

I can post the code for the app if that helps

Thanks for any assistance with this

Yes we need ot see application and error messages.

CORS is tricky for cross-domain URL references, which I am assuming is what you have here.

The new IDE gives every new deployment a new URL; so that may have broke it (?? --just a guess). If you go back to the deployment that was working, and update that one (deploy it again with your updated code), the URL should remain the same and in theory, should continue working properly. This is all speculation, so I apologize if it doesn't fix your problem.

Yes, that worked.  I did not realize that you could redeploy, I thought you had to make a New deployment.

And when I redeployed I saw that there was a library attached to the project which I think was handling the CORS

Thank to both oy you!
