Hi,

I have encountered this issue at least 2 or 3 times now. I am not sure why it happens or how to diagnose the issue? Any help would be appreciated.

Hi @bceyresy

have you installed any new nodes recently? Or tried to create your own nodes?

Yes I installed a few in fact. Last time this happened I removed the modules from the .nod-red directory in the current user, then also removed the lines corresponding to the modules called in .config.nodes.json but this time it has not solved the issue. I think I got lucky last time.

Please shine some light on it :upside_down_face:

This error is 100% caused by a 'bad' node somewhere.

You don't need to delete .config.nodes.json - that is just a record of what has been found.

Are you sure there isn't left behind in .node-red/node_modules?

5

Ye I have deleted the last recent 3 I installed and used. It still will not boot.

There are 2 module folders, one in the .node-red & one under AppData\roaming.

Whats the difference between the 2?

Found the bad note. It was cratedb. I Had the same issue with Postgres nodes. I am using Mysql at the moment. is there issues with installng other DBs?

7

What module name exactly? I'd like to track down nodes that cause this so we can either get them fixed, or remove them from the flow library.

8

it appeared to be node-red-contrib-cratedb was this instance. I can't remember exactly which postgres node was the issue last time as I installed quite a few together.

Thanks

Sy

@knolleary node-red-contrib-cratedb was last updated over four year ago and in GitHub the author has archived it.

Yes. I looked it up as well.
