What are possible causes for this warning appearing intermittently on the IDE. The application on OpenMV H7 plus seems to be displaying fine.

This error is arising more often now on the IDE and the application on the H7 just freezes while the error is occurring.

There is no line in the code provided. How can I debug this issue?

The jpeg image is too big to fit into the JPEG buffer on your OpenMV Cam. Reduce the JPEG quality or resolution.

The only issue when you see this error is that your frame rate will now be locked to the transfer rate to the IDE versus being async. So, you will see performance degradation.
