python-eel
connection to 'ws://localhost:8000/eel?page=main.html' failed: Could not decode a text frame as UTF-8.
Eel version
0.12.2
Describe the bug
Occasionally loses WebSocket connection because of this error message connection to 'ws://localhost:8000/eel?page=main.html' failed: Could not decode a text frame as UTF-8.. This is happening when sending pretty large arrays to the front end
To Reproduce
send (1024x256) multidimensional array from python backend to the javascript front end like so eel.sendData(arr) until the error is produced (will not happen first time, seems to be random)
Expected behavior
Websocket does not close because of encoding error

By the way this appears to be caused by the javascript side calling eel before the last eel call has completed. I solved it by implementing a mutex on the javascript front end but Im sure there is a better way to do this in eel backend
I am running into this same issue. Could you describe more how you implemented the mutex on the JavaScript front end?
