Where is this update error coming from? I just wonder if it'd be cleaner to avoid the operation if there are no parallel corpora or otherwise change it.

When a DataFile is being updated, it syncs the filename to the corpora and parallelCorpora. The old records in the database don't have parallel-corpora, and when the update is pushed, it cannot filter because the field (parallelCorpora) does not exist. This adds it on startup (migration) ensuring that the update operation can work.

At some point, we probably want to store a model version in the DB, so that we only run the migration if we need to.

@Enkidu93 We did not mark the new ParallelCorpora property as optional in the model in the mixed source PR.

OK, yep, that's a good point.
