Error starting subflow

General
1

I am using node-red with home assistant and during a recent upgrades it caused node-red to start crashing. looking at the logs I found this error I couldn't get rid of. Not sure where to look the stack trace points to Subflow a not being able to start, but what should I look for in there? functionally everything seems to be working.

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

Exactly what version of Node-RED have you got? Check the bottom of the main menu in the Node-RED editor - the home assistant packaging uses different version numbers to those we use.

Running 3.0.2. and HA-Addon version is 13.3.1

bit more trace logging if that helps identify which flow/node is causing me grief.

@knolleary added some trace logging. not sure if this is red herring.
