Have tried docker compose to run node-red container and a postgres container together (the db container is not accessed yet and irrelevant for node-red at the moment). Everything is running fine, except the Project feature.

The docker setup consists of a slightly modified version of the official node-red custom docker ([node-red-docker/docker-custom at master · node-red/node-red-docker · GitHub](https://github.com/node-red/node-red-docker/tree/master/docker-custom)), built with docker compose and dockerfile. Using bind mount for /data as normal, but otherwise no dedicated volume (didn't see a need for it).

When navigating to Projects --\> Project Settings in web browser, web browser console gives following error:

```auto

Any clue what is wrong, or what I might have missed that causes this problem?
