`ota_mqtt` example not working for esp32-wroom-32d (DevKitC v4) (CA-325)

[gamename]

Hi,

The example compiles and flashes fine. When I run an OTA job from AWS this happens:

1. The esp32 appears to download the firmware
2. But at the end of the download, there are errors
3. The AWS job marks this as a failed OTA attempt

The relevant errors are:
