What it means

A model reference that no catalog the runtime reads knows.

What to do

Look in params.suggestions for the model the reference most likely meant, or list the runner's models with GET /models, and correct the reference.

Next steps

A problem carries the step aimed at whoever reads it: the first when its reader is the domain's actor, the method's author, and the second for any other reader.

Reader	Kind	Detail
The domain's actor	`change_model`	Name a model that exists in place of '`{model}`', then run the method again.
Any other reader	`contact_owner`	Ask the method's owner to name a model that exists in place of '`{model}`'.
