Hi everyone ! I’m using nested pydantic models as input parameters for my flows. My issue here is that I’m blocked by mandatory field in optional nested model: My input looks like :

class ModelB(pydantic.BaseModel):
    mandatory: string

class ModelA(pydantic.BaseModel):
    some_values: typing.Any
    b: ModelB | None = None

In some case, I don’t need to instantiate

ModelB

and to do so, I just don’t add it to the deployment’s yaml. This was working fine all along, but this morning the UI prevents me to run a deployment

Quick Run

as my field

ModelB.mandatory

is missing (even if I did not specify

ModelB

in

ModelA

in the yaml). Did something change and I have now to change my model parameters ?
