`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:

Here is the log.

Hello @gamename,
I went through the attached log and it seems that the firmware version of the OTA is the same as that of firmware flashed into the module. Try changing app version of the OTA firmware from here.
