Hi @pksofttech, are you trying to serialise the MQTTConfig with a SSLContext defined? (it's not possible)

Could you give some details about your environment? (python, pydantic + fastapi-mqtt versions, etc.) and when/how this is happening?

Closing this one, as deprecated.

In current v2.1.1 the MQTTConfig(BaseModel) already has the model_config = ConfigDict(arbitrary_types_allowed=True), and, unless trying to serialise to JSON with an SSLContext, there are no known problems about ✅
