Getting the following error after pasting in an example flow from

> <https://github.com/dceejay/RedMap/blob/master/examples/Basic%20Map.json>

Flows stopped due to missing node types

- os-config
- tjbot-config
- wiotp-credentials

Deleted example flow - same error.  
Deleted all flows - same error.  
Restart node-red - same error.

Is there any way to fix this without re-installing Node-red???

Node-red v1.2.6 running in WSL2.

Open the Configuration Nodes sidebar, look for any 'unknown' nodes in the list and delete them.
