Help Needed module_not_found

General

Hi!

I don't know how I lost the worst possible module in node-red :cold_sweat: : node-red-contrib-home-assistant-websocket.

I'm running node-red on docker but I initially created it through the synology interface of docker and wanted to use a docker-compose instead of using the interface. I did a backup of the 'data' folder... so I thought, easy, just stop/delete the container from the interface and then re-create it with docker-compose (pointing to the same 'data' folder as before) but when I restarted it ONE (and only one?) module was not found anymore (the home-assistant-websocket... which I'm using for almost everything :sob: ).

I really hope someone can help me restore that because I would lose 2+ days of configuration :scream: .

When I start node-red, I can see the following message:

I checked in the backup folder but cannot see this 'websocket' folder??

Thanks for any help!

Holy crap, I was finally able to recover it... not sure what was missing but here is what I did:

  1. Created an empty node-red container
  2. Added the node-red-contrib-home-assistant-websocket module
  3. Created some basic flow/nodes which is using the module (not sure this is required)
  4. Deploy changes
  5. docker-compose down
  6. Copied all content of the node_modules folder to the nodes_modules folder of the container which was not working
  7. docker-compose up on my 'real' container
  8. Grab a beer and enjoy it :heart_eyes:

So happy right now :laughing:
