Hi, I'm getting these warning in the log after running for a while:

I tried to reproduce this but I think the issue is nolonger there. I see:
HTTP GET /api/v1/firmware-upgrader/build/216caba4-cbf0-485e-8d34-be87a1c32675/image/feb0ca62-536d-4fa4-9acf-f78353a6376c/ 200 [0.04, 127.0.0.1:48468]
And no traceback in the console where django is running. Should I be looking somewhere else?
