Description

Hey, I know this issue has probably been dealt with before, however I can't find any proper workarounds to it.

I'm getting this message: Unchecked runtime.lastError: Could not establish connection. Receiving end does not exist.

when I running my main.py

here's the code:

JS image

Python image

HTML image

and I really confused 'cause everything looks fine...

Any help will be very appreciated in advance.

Contributor guide

Research direction
Investigate the 'Could not establish connection' error. Check if the JavaScript is calling an exposed Python function correctly and that eel.init() is called with the correct web folder path. Also verify that the Python script calls eel.start() and that the browser is not blocking the connection due to extensions or CORS.
