I think you might have come across a possible bug. I feel you may be running into version compatibility issues of the node if you’ve copied from somewhere?
Can you try:
Recreate using the nodes sidepanel (no copy+paste workflow). This should ensure you’re working with compatible versions of the nodes.
Switch to the tools agent instead rather than the conversational agent. Tools agent has been the default from a few releases now and should do a better job with tools.
Ah ok, I just updated to 1.54.1 and yes, it’s currently breaking from me as well.
Would advise downgrading temporarily to 1.53.0 which works for certain.
