Still problems with Langgraph tool use example... Error: Unknown content part type: [object Object]

[GregorBeuster]

[ { "content": "merk dir dass 1,92m gross bin", "additional_kwargs": {}, "response_metadata": {}, "type": "human", "name": null }, { "content": Array, <-- THIS COULD BE THE NEW PROBLEM? "additional_kwargs": {}, "response_metadata": { "stop_reason": "tool_use", "stop_sequence": null }, "type": "ai", "name": null }, { "content": "Stored memory None", "additional_kwargs": {}, "response_metadata": {}, "type": "tool", "name": null }, { "content": [ { "text": "↵↵Vielen Dank für diese Information!", "type": "text", "index": 0 } ], "additional_kwargs": {}, "response_metadata": { "stop_reason": "end_turn", "stop_sequence": null }, "type": "ai", "name": null } ]

When I try to display this thread containing 4 messages, I don´t get the error regaring trim function not defined anymore but a new one:

Error: Unknown content part type: [object Object]...

Thanks. Hmmm... there is a bug in the error message code, which is why you're seeing [object Object]

I have fixed the bug, so if you upgrade, we will see the correct error message. (@assistant-ui/react-langgraph@0.0.17)

Could you console.log(JSON.stringify(values, null, 2)) so that we see what's inside the mysterious Array? Somewhere inside of this array, there is an unrecognized type

So it's the "tool_use" content part that is confusing assistant-ui - thanks for catching this!

Just fixed in #994 / @assistant-ui/react-langgraph v0.0.18

Can you confirm that this is fixed? Thanks a lot and sorry about the back and forth!

[GregorBeuster]

Fixed :-) Many thanks man!!!

[Yonom]

Amazing :)
