KNIME 5.7 Agent Chat view - Tool call observability issues

[MartinDDDD]

Hi all,

took some time tonight to test out the new 5.7 Agent Chat View that includes additional information about tools being called.

I observed the following:

• Did not work, when Agent Chat View is embedded in a data app
• Did initially not work, when running Agent Chat View - After unchecking “Show tool calls and results”, applying that change, then checking it and applying it again, it worked
• When I then opened then closed the chat window and opened it again, it did not work again and I had to repeat the uncheck/check workaround above.

I created some screenshots to replicate and here is what happened:

1. Opened it and it worked:

   

2. Closed it and opened it again, it did not work (no config changes)

   

3. Closed again and opened again w/o config changes to confirm:

   

4. Closed it, did the uncheck/apply/check/apply workaround and it worked again:

   

Other than that - awesome new feature

Hi Martin, many thanks for reporting (and using the feature )! And apologies for the flakiness there.

We have these on our radar already, will get the fixes in for 5.8

Hi!
I was comming to make some of this observations.

• It takes so long to respond, when it does it
• It don’t show the initial message
• It seems that doen’t work well with Gemini LLM
• I managed to make a componet with a header and Published it as dataApp in KNIME Pro, but It worked poorly, and responded with so many errors.
• Testing the example 01 Simple Agent didn’t answer well, like It couldn’t interact with the tool. I tested in AP, asking it in English and Spanish and had the same problem.

Thanks!

It seems that doen’t work well with Gemini LLM

I think @ActionAndi tested the prior versions with Gemini as well and from memory he had to tweak the default system message slightly to get it to work more reliably.
