Extension manifest not working in Flask

Extensions
1

I created this File Navigator extension, which uses Python’s Flask to serve the static pages. However, I could not add a manifest to it, and I get an error saying “Failed to load extension manifest”. I also tried LuisAFK’s Replit Extension Manifest Checker, and it says:

Missing manifest.icon
Invalid manifest.website: must be a valid URL
Missing manifest.longDescription

Extension icon:
Cover images:

To reproduce this, add an extension by URL and paste in “https://File-Navigator.drrman.repl.co”.

Does anyone have any advice on how to fix these errors?

That Repl doesn’t have an extension.json file…

I’ve updated my manifest checker. But the error is that the version field is a WIP and can only be zero for now.

I tried adding it, but I still don’t have any luck. I tried doing this as well:

Might be a CORS issue?

Yeah. I updated my code to use the flask-cors library, and it worked perfectly. Thank you for your input!

In the future, I hope you realize you can just use a header, instead of installing a entire library.

Wait, what do you mean?

You just needed to add this header to your response: Access-Control-Allow-Origin - HTTP | MDN

No need for the library, as CORS is enabled by default on most browsers.

OK. How do I add a header in my code?

Check the flask documentation.

Next time, as @9pfs1 said, just check the docs or google. But here you go for the google answer:

Darn, you got marked as the solution when I mentioned CORS first. Though I suppose you were more helpful =P
