Hi, I usually get error as following.

Any one know why?

  • Mode: Gemini-2.0-flash-thinking-exp-01-21

  • Vertex AI

ERROR Unable to submit request because it must include at least one parts field, which describes the prompt input.

Hi folks,

It seems it’s not detecting the prompt properly. I looks an intermittent issue, Can you start a new chat and check if it’s still happening.
