Proposed fix: [Google Gen AI SDK local tokenizer (Go/Java)] 'downloaded model hash mismatch' / 'Downloaded model file is corrupted. Expected hash ...' — tokenizer model fetched at runtime from raw.git
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Allow raw.githubusercontent.com in egress, or pre-seed the cache file ($TMP/vertexai_tokenizer_model/<hash of URL>) in the image; ensure the temp dir is writable; fall back to the countTokens API if local counting is unavailable.
Option: Pre-seed or allow the tokenizer download [evidence: official_recommended_action]
Steps:
1. Allow raw.githubusercontent.com or bake the cached model into the image.
2. Make sure the temp dir is writable.
Expected: Local counting works offline.
