```

Is the error a problem in the telegram node? Is it possible to deactivate such nodes by hand?

Start node red in safe mode `node-red --safe`, then you can disable or remove the nodes that give the problems.

After starting in safe mode use Manage Palette to make sure that all nodes are up to date. Particularly the telegram node obviously, in case you have encountered a bug that has already been fixed.
