TypeError: Cannot read properties of undefined (reading 'hasOwnProperty')

General
1

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:

  1. I pull the latest image and run the container.
  2. 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).
  3. After selecting the project, the error above occurs in the logs docker logs <container-name>
  4. 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:undefined in the UI.
  5. 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!

There will likely be more than just TypeError: Cannot read properties of undefined (reading 'hasOwnProperty') perhaps a stack trace or at least the log entries before and after it (so we can see what part of the loading phase it occurs or any other errors/warnings for contextual purposes)

FWIW, your settings file works on a clean Node-RED 4.1.0 beta.2 (after a changed the "credentialSecret": “test” to "credentialSecret": "test" (bad quotes) and I can create a project.

please capture a screenshot

This suggests not everything was in place correctly (some files missing? or different values?) and a few restarts has allowed it to sort itself out. I am not saying this is expected or right, just what appears to be happening. So, I would suggest forget docker for a moment, install Node-RED natively and run it with your settings.js, create an project named app and then make sure you capture all files from the .node-red dir (especially creds & config json files) and make sure they are copied to your docker container.
