Proposed fix: [Vertex AI SDK] response.text raises 'Cannot get the response text.' / 'Response has no candidates (and thus no text). The response is likely blocked by the safety filters.'
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Inspect response.prompt_feedback / candidates[0].finish_reason and safety_ratings before reading text; handle function_call parts separately; iterate candidates when candidate_count>1.
Option: Check finish_reason and parts before .text [evidence: documented_workaround]
Steps:
1. if not response.candidates: inspect response.prompt_feedback.block_reason
2. cand = response.candidates[0]; check cand.finish_reason
3. read text from parts that have text; handle function_call parts
Expected: No ValueError; blocked responses handled explicitly
