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:
```auto
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 `
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.

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.

Hi @Steve-Mcl,

Seems you are right, I regenerated all the files and folders by creating a project from scratch fixed the problem.
Thank you!

Hey i'm having the same exact issues as you and two times restart fixed the problem just like you are
[bigbean17](https://discourse.nodered.org/u/bigbean17) erm , may i know what do you mean by regenerated all the files and folders and start from scratch ?
As for my case , I mount the /data/projects to host filesystem and then i try to restore it from the backup volumes that i mount but i need to do restart two times to make it render the flows , could you please advice what do you mean by regenerating all the files back ? do you manage to make it work with docker ?

Hi,
Sorry for the late reply.
Yes, I regenerated everything from scratch (installing node-red, enable projects and copy-paste all the my flows.)
Yes, it works with Docker. There is a node-red docker example, I started from there, to verify it is not the issue with node-red or docker itself. Then, you regenerate all the files and add them to the docker. If that works well, copy-paste your existing flows to the fresh node-red instance and install all the missing dependencies. It should be work afterwards.
Hope it helps.

And from what I found, it seems like the issue was caused by the file `.config.projects.json` is missing. I ignored all the .config except that file and everything works fine now.
