ReAct Agent with OpenAI does not call tools

Questions

Hi Dear Community!

I need some help with understanding how does ReAct Agent calls tools.

When I use OpenAI chat model (gpt-4o), sometimes Agent does not call tool, but tries to output final result, even though it is not final yet.

For example:

Here the output of model clearly says that sabre_command tool should be run. However the tool is not run, and agent tries to parse to JSON. And as result failes with error:

If I use Anthropic chat model everything works fine.

n8n version: 1.74.0

Please help!
