Issue
The Gemini API was receiving requests with empty content parts when used in complex flows in Seq Agents, causing a 400 Bad Request error.
Root Cause
The
convertAuthorToRolefunction was incorrectly mapping function/tool messages to 'user', causing message merging logic to create empty content parts when tool interactions occurred.Fix Compatible with Multi-Agents too
