No entities found; create your models first!

I have my model "outsourced" into a gem and used to start rails-erd like this:

 bundle exec rake erd inheritance=true --trace

I suppose since the upgrade, this doesn't work for me anymore and I do get this error:

** Invoke erd (first_time)

Any ideas what might be wrong?

Please see my comment here: #42 (comment)
If you're able to send the complete application (or at least models + database schema) that would help too.

Fyi: I tried to downgrade to 1.0.0 but still no luck it is still broken. I previously thought it might be broken since the new version came out. For me now this looks like as if an other application/ gem did broke it.

I have to check what I can send you and will report you back

[phlegx]

Unfortunately it is impossible for me to send the whole model. Not sure how this can be debugged then.
