Every time I deploy I get....

Reading through it seems to be a flow causing the issue, I've deleted flows then re added them, looked into each flow and buit it back. I've created new flows with different content, then the issue comes back over time.

I've taken the flows.json file accross to my dev pi that is running Home Assistant and Node red in the same way the prod box is and it crashes. The home assistant build on the dev box is completely empty.

my prod box is a pi 4 8g and my dev box is a pi 4 4g.

Just can't work out what is causing it.

Running 10.0.1 node red

Core
Version
core-2021.10.4

Supervisor
Version
supervisor-2021.10.0

Operating System
Home Assistant OS 6.5

What happens if you start it in safe mode?
Node-red —safe

Hi Zenofmud,

Thanks for the reply. I've read about safe mode, but can't work out how to activate it in a Home Assiatnt / Node Red setup. do you know?

Sorry, I don't use Home assistant so I don't know. You might post that question on the Home Assistant forum...
