Thanks for the report. We've identified the exact data entries that trigger the errors—they follow the standard format using role: system and role: user. We also verified that the same inputs can be processed successfully using other APIs without any issue.

Given this, it appears the errors (INVALID_ARGUMENT, code: 400) are specific to Gemini 2.5 Flash, not due to malformed input on our side.

This suggests it's an issue on Gemini's end. We recommend escalating to the Gemini team for further investigation.
