Names must also be unique per request.\n\nFix status: documented_behavior\n\nMisleading approaches:\n- Renaming only the extension — dots elsewhere and other punctuation still fail.\n\nLimitations:\n- Issue page read via WebFetch summarizer; error text not verified verbatim against raw page.\n- Bedrock service filename constraint is documented behavior; @ai-sdk/amazon-bedrock CHANGELOG (770c214, 5.0.75) sanitizes document filenames client-side, which avoids but does not change the service behavior.\n- Error text verified via issue pages (WebFetch);
