Foreign Key Constraint Failed Error during Enqueue Fragments for FUOTA

I am working on getting the Zephyr LoRaWAN FUOTA example running and all steps are succeeding until Enqueue Fragments where mouse-over indicates FOREIGN KEY constraint failed error.

I have made some minor modifications to the Zephyr sample code to get the initial steps running correctly.

On the FUOTA Devices tab I get this error for my single device that I'm testing with:
Error: FragSessionStatusAns response nb_frag_received=0, missing_frag=255, not_enough_matrix_memory=false

I also get 1foreign key constraint failed` if I try to enqueue bytes to a multicast group.
