Data page shows Counter and Tracker while counting, but goes blank after counting [Jetson Nano, JetPack 4.3]

I installed ODC 3.0.1 on a Jetson Nano via the Docker method. When I access ODC via http://192.168.0.11:8080/ and upload a video file to count the vehicles, it seems to work. However, the Data tab / area is blank at the beginning, has content during Recording, and goes blank again after the recording. I thus cannot download the data.

The counts from the Counter view seem to be correct though. The Console gives a ton of errors like the following: (node:119) UnhandledPromiseRejectionWarning: Unhandled promise rejection. This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag –unhandled-rejections=strict (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 6549) (node:119) UnhandledPromiseRejectionWarning: MongoServerSelectionError: getaddrinfo EAI_AGAIN mongo at Timeout._onTimeout (/var/local/opendatacam/node_modules/mongodb/lib/core/sdam/topology.js:430:30) at listOnTimeout (internal/timers.js:549:17) at processTimers (internal/timers.js:492:7)

Should I download the data midstream, even if the recording is still “Ongoing”, so I can download the data?

I think I did. Looking back, I’m not so sure now. 😄 I’ll try giving it a whirl again. 😃

Ran into the same issue. When I tried to install another instance of a docker container on my Synology NAS to point opendatacam to use it I saw the error message that the CPU was not supported for Mongo v5. Downgraded to 4.x and it worked flawlessly. Also when I did this on the Jetson, all was well. So indeed, it is a hardware support issue, mongo 5 introduces more requirements re: the CPU it is willing to run on. 🤷
