Incorrect "Missing required parameter" error?

[danielniccoli]

I migrated this handler from FastAPI to Litestar.

@post("/securitygroup")
async def security_group_create(
    group_request: SecurityGroupRequest, # SecurityGroupRequest is a Pydantic model/class
    x_ms_client_principal_id: Annotated[
        str, Parameter(header="x-ms-client-principal-id")
    ],
    x_ms_client_principal_name: Annotated[
        str, Parameter(header="x-ms-client-principal-name")
    ],
    request: Request,
) -> RequestResponse:
    ...

It was working fine with FastAPI, but now I get a response

{
    "status_code": 400,
    "detail": "Missing required parameter group_request for url https://localhost:7071/securitygroup"
}

This is the request, with which it worked under FastAPI but now fails with Litestar:

curl --location 'http://localhost:7071/securitygroup' \
--header 'x-ms-client-principal-name: DiegoS@test_HywWv.onmicrosoft.com' \
--header 'X-MS-CLIENT-PRINCIPAL-ID: cb1fd552-401d-4aea-ade0-6cbf5b747f80' \
--header 'Content-Type: application/json' \
--data-raw '{
    "owner": "DiegoS@test_HywWv.onmicrosoft.com",
    "deputy": "DiegoS@test_HywWv.onmicrosoft.com",
    "display_name": "Cool New App!",
    "description": "This app does something very cool!",
    "mail_enabled": false,
    "security_enabled": true
}'

How do I fix it?

The request body variable has to always be data as shown here.

The body of HTTP requests can be accessed using the special data parameter in a handler function.

Does changing group_request to data in the route security_group_create work?

Yes, thank you!
