Here’s what’s happening:

When I try to create a new Web app on my Appwrite console (backend.keplr.in), the browser console shows multiple errors:

Uncaught (in promise) SyntaxError: Unexpected non-whitespace character after JSON at position 4 (line 1 column 5) Uncaught Error: Extension context invalidated. Failed to load resource: net::ERR_BLOCKED_BY_CLIENT GET https://backend.keplr.in/versions 404 (Not Found)

The errors repeat several times and the app creation doesn’t complete properly.

Setup details: Appwrite: Self-hosted Platform: macOS Browser: Chrome

Using Appwrite Console to add new Web platform under project keplr-backend

The endpoint is accessible at: https://backend.keplr.in

If anyone has seen this before or knows what could cause this issue (maybe something wrong with the API route or CORS settings?), I’d really appreciate your help 🙏

Thanks in advance!

TL;DR
Facing JSON and extension errors while creating Web app on self-hosted Appwrite setup. Errors in browser console: JSON SyntaxError, Extension context invalidated. Also, GET request to /versions returns 404 error. MacOS, Chrome. Possible API route or CORS issue. Endpoint: https://backend.keplr.in. Any solutions?
