@leocg there should be way to generate some new hash files (instead of supposedly throwing this error) so modified extension will be accepted as valid extension

I guess it's this file

/<extension>/<version>/_metadata/computed_hashes.json

Whenever I try to modify extension source code, I get following message after restart:

Your extension was disabled because it is corrupted. Go to the extensions manager and repair it.

And not able to run modified extension.
Is there any way to prevent this?
