Error processing request: SyntaxError: Unexpected token ',', ...""ai_dump":, "Image":"... is not valid JSON

Hello All,
Just had this set up, and ran into errors when manually triggered from Blue Iris:

5/25/2025, 7:22:58 PM [INFO] POST /api/plate-reads
5/25/2025, 7:22:58 PM [ERROR] Error processing request: SyntaxError: Unexpected token ',', ...""ai_dump":, "Image":"... is not valid JSON

I have below Blue Iris's Post/payload:

{ "ai_dump":&JSON, "Image":"&ALERT_JPEG", "camera":"&CAM", "ALERT_PATH": "&ALERT_PATH", "ALERT_CLIP": "&ALERT_CLIP", "timestamp":"&ALERT_TIME" }

Am I missing something?

Hi,

From the error message it seems that Blue Iris isn't sending anything in the &JSON part, which is normal if you triggered the message with the test button within the "On Alert..." window. You can try to catch the message sent with Fiddler or similar software to see what actually is being sent from Blue Iris. Or output the &JSON to some file and see if it contains anything.

Thanks for replying. It seemed to work OK now once BI ALPR triggered with plate found. Thx
