REST migrate/validate returns empty instruction set

Hi there, I wanted to migrate a process definition that contains 1 single process instance. When I invoked

POST …/migration/validate

the return was an empty list:

{
“instructionReports”:
}

The process instance in question is waiting in an internal sub process:

any idea what went wrong?

@cjacob how does your migration plan looks like? Can you post the migration plan?

This is the migration plan:
