exec: python3: not found

After upgrading my docker containers today I started to receive a python3 error. Below is the section of my docker compose file as well as the relevant log lines. The last section just keeps repeating. Everything goes back to working if I change from latest to v5.0.0

Interesting. I just built a new latest from Docker Hub, pulled and it was missing python3. I then turned off “Build Caching” and ran another build and it appeared. I’ll do some research why this would be happening - but in the meantime I’ve turned it off entirely and the image should be usable again, sorry about this!

Amazing thanks for the update. I’ll pull the new image and use that. For reference, this is the has that was causing issues: sha256:82a583ee1771024c89e3865daf453244a70da82c4ce87da4a8b0b527505dd753
