Uncaught TypeError: Cannot read properties of undefined (reading 'buffer')

After trying to search for the value 100 I get this error in the extentions I am using Opera GX and I have tried this in Chrome The search also never ends

When I add the extension I get this error:

Manifest version 2 is deprecated, and support will be removed in 2023. See https://developer.chrome.com/blog/mv2-transition/ for more details.
"manifest_version": 2,

Console error when I search:
