Successful response has body. An optional client_secret (not required for our example). Method return values are sent back as RPC responses, which the other side can wait on. Our way of writing this test will involve the following steps: 1. As seen in the above code, you need to await the info.json () to read the JSON data. You signed in with another tab or window. The developers behind FastAPI work around the issue with some tricks to handle the compatibility as well as incompatibilities between OpenAPI, JSON Schema, and OpenAPI's 3.0.x custom version of JSON Schema.
