Generated diagram isn't loading all models

[kenton]

Trying to generate an ERD for a project I'm working on and keep getting errors like these:

Warning: Ignoring invalid association :survey_questions on Program (model SurveyQuestion exists, but is not included in domain)
Warning: Ignoring invalid association :saved_matches on Program (model SavedMatch exists, but is not included in domain)

There are a ton of these and the resulting diagram is missing all of those tables (which makes sense, given the warnings).

Just not sure the cause or fix for this. (FYI upgrading to Rails 6.0+ is not an option at this point)

Thoughts?

Models should be migrated before generating erd.

Same here, migrations are done

All migrations are done but this error still persists. How do I force all models to be included? I don't care about domains, this is legacy code and I just want to understand it so I can make updates or replace it with new code in a different project.
