Based on the error traceback you provided, this appears to be a bug in the Frigate API code where there's a type mismatch when handling the best.jpg endpoint. The specific error shows: This occurs in the Similar internal server errors have been reported with other Frigate API endpoints. There was a related issue with preview GIF endpoints that also resulted in server errors due to missing data (1). Additionally, there have been other reports of 500 Internal Server Error responses from various Frigate API endpoints (2). This appears to be a code-level bug in Frigate version 0.16.1 where the thumbnail API endpoint is not properly handling the file extension parameter, causing the server to crash when trying to generate thumbnails for certain events. Since this is affecting the core API functionality and appears to be a regression or bug in the current version, you should report this issue to the Frigate GitHub repository with the full error traceback you provided, as it contains the specific code path and line number where the error occurs. 📚 Sources:
