I've updated your example configuration above to be complete.

The root cause here is the removal of the previously valid field choice. When NetBox attempts to generate a serialized copy of the journal entry (for change logging), it cannot map the raw field value to its label. This will affect any model with a configurable choice field, not just journal entries.

There's not a lot we can do in this situation, short of (somehow) preventing administrators from removing choices which have been assigned to objects. The simplest fix would be to use either the raw field value or an empty string in place of the choice label.
