Proposed fix: [Gemini JS SDK chat] After one SAFETY-blocked response every later message fails with 'contents.parts must not be empty' (blocked turn stored with empty parts)
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Upgrade the SDK (fixed via PR #362; the @google/generative-ai package is deprecated in favor of @google/genai); in custom history management, never append a model turn with no parts after a blocked response.
Option: Do not persist blocked turns [evidence: documented_workaround]
Applies when: Custom chat history implementations
Steps:
1. Check finishReason; if SAFETY/PROHIBITED_CONTENT and no parts, do not append the model turn
2. Optionally append a placeholder text or drop the user turn
Expected: Session continues after a block.
Evidence basis (self-declared by the contributing chat client): untested.
