Flows stopped due to missing node types. nodebot

Greetings , after trying to use node-red dashboard i got the following error .

" Flows stopped due to missing node types.

I've tried to completely remove node-red from my system , but with no luck.
Everytime i refresh the localhost:1880 node-red loads again with the same error.
If you need any other details please commect below.

I'm new to linux so every advice/suggestion is appreciated.
Thanks in advance.

I think the fix is here.

Thanks that seemed to fix the issue.

Best regards,
Chris
