I am trying to package a firmware update and flash it over BLE DFU and I keep getting the following error on the nRF Toolbox app:
"Upload Failed: Unknown Command"
I cannot figure out why this is happening and I can't find anyone else having this error on here. Here are the commands I used to create the initial bootloader and settings (flashed over J-Link).

After flashing the softdevice and the bootloader, here is what I used to generate the package file:

nrfutil pkg generate --application ../AKDP/BUILD/AKDP_RevE.hex --application-version 21 --hw-version 52 --sd-req 0x9D,0xA5 AKDP_RevE_with_BL_pkg.zip
Other information:
- Device: nRF52832
- SDK: 14.2.0
- Board: Custom
I cannot understand why this isn't working. It all looks fine to me. The bootloader build completed without any problems. Any help would be greatly appreciated.
