ERROR 500 After Cache Clear when using API (SOLVED)

[Tahor]

After installing this and clearing the cache using php bin/console cache:clear it successfully cleared and the plugin installed, but my n8n API was refusing to work and I kept getting error 500.

Using this code right after clearing the cache seemed to fix my problem rm -rf var/cache/*

I'm running this in a Docker container if anyone is wondering using 5.2.3 -- fresh install

Wanted to post here in case it helps someone else.
