Describe the problem/error/question
I’m trying to use AI Agent.
Connection to Ollama works fine.
When using “Basic LLM Chain” works as expected.
But, when using AI Agent something strange happens: The node executes for about 5 mins and then raise an error (shown below).
When the error is raised, the “Ollama Chat Model” node shows 2 outputs, the first one is success and show the follow output:
obs.: I asked “What is the square root of 49?”
first success output

It looks like a internal conversation.
Also, in the Ollama server there’s this error message:
