Rasa in Docker: Could not load model due to Error deserializing graph schema

When deploying Rasa service in production Docker environment, error show:

rasa.core.agent - Could not load model due to Error deserializing graph schema. Can't find class for graph component type 'rasa.graph_components.providers.forms_provider.FormsProvider'

Reason

This error typically occurs when there is a mismatch between the version of Rasa used to train the model and the version used to load the model. It's possible that the model was trained with a newer version of Rasa that introduced a new graph component type (in this case, 'FormsProvider'), which is not recognized by the older version used to load the model.

e.g.

• dev: 3.6.7
• docker: 3.1.0

Solution

Pull new version of Rasa docker same as dev enviroment.
