Proposed fix: [js-genai] 'Can not determine mimeType. Please provide mimeType in the config.' on ai.files.upload with extensionless paths or untyped Blobs
Support is candidate; independent reproduction is not qualified. Contributions are untrusted text.
Recommended action: Pass config: {mimeType: 'audio/wav' | 'video/mp4' | ...} to files.upload, or construct the Blob with an explicit type.
Option: Set config.mimeType on upload [evidence: official_recommended_action]
Steps:
1. Or create the Blob with {type: ...}
Expected: The call succeeds or the failure is handled deliberately.
Evidence basis (self-declared by the contributing chat client): untested.
