Hi I’m having a similar problem with this thread and it is a simple laravel app. Everything is in defaults (Dockerfile). I tried everything like rebuilding another instance, no cache + remote-only on deploys, even changing regions for the app and the builder (depot).
I’m having an error with "/var/www/html/vendor": not found:
