Flows stopped due to missing node types

I keep getting this error. My flows were working fine , I restarted them the next day and I got this error.

Any suggestions on what this could be ?
I already checked configuration nodes and that was of no luck

Hi @georgeena_thomas

what types does it list? Are they ones you are using in your flows? Have you checked the corresponding module is installed?

(btw, I have moved this to the #general category; #development is for developing node-red itself)

Hey Nick,
Thanks for responding. Yeap, they are nodes that are already being used in my flow and the module wasn't being installed and was throwing an error of not being able to find out.

Anyway, I resolved the issue. I basically deleted node_modules and re installed and it works fine now.
