Hi all,
I'm trying to deploy my Node-RED app (with projects enabled) using Docker, but I keep running into this error on first launch:
TypeError: Cannot read properties of undefined (reading 'hasOwnProperty')
My goal is to have the project load automatically. Here's what happens:
- I pull the latest image and run the container.
- On first launch, Node-RED asks me for my username and email, then prompts me to select a project (my project appears in the list).
- After selecting the project, the error above occurs in the logs
docker logs <container-name> - I then restart the container. It asks for username and email again, and prompts for project selection. This time, the project selection dialog stays stuck, and I see a warning like
undefined:undefinedin the UI. - I restart the container one more time, and everything works normally.
This happens every time I pull a new image and start fresh.
Any ideas on what might be causing this or how to avoid it?
Thanks in advance!
