Hi, as this has been working fine for … quite some time, can you get me the versions and an MRE to look at? |

Hey @commonism, I’ve been working with these packages for over 6 months. I may have recently upgraded FastAPI or another dependency, but suddenly I started getting the errors I addressed in this fix — and it happens with any openapi.json I’m provided. versions are example of json: {

pydantic 2.11.0 broke it in quite a lot of places, this is only one of them Here is the relevant change to pydantic - pydantic/pydantic#11032, it's in the "spacebar heating" stage. You'll have to nail pydantic to <2.11.0 for now |
pydantic.warnings.PydanticDeprecatedSince211: Accessing the 'model_fields' attribute on the instance is deprecated. Instead, you should access this attribute from the model class. Deprecated in Pydantic V2.11 to be removed in V3.0.

While I'd prefer pydantic taking responsibility for this regression, let's roll with this for now. Thanks for notice. |
