When defining your payload
Body
parameter like this:
payload: dict = Body(...)
and since it is the only Body
parameter in your endpoint, FastAPI will expect a body
like:
{
"some key": "some value"
}
Since you have a single body
parameter, you could also use the special Body
parameter embed
:
payload: dict = Body(..., embed=True)
in which case, FastAPI would expect a body
like:
{
"payload": {"some key": "some value"}
}

When sending the request through Postman
Also, the 422 Unprocessable Entity
error shows that the body
received doesn’t match the expected format. Hence, please make sure you are posting the request body
through Postman in the right way. That is, go to Body
-> raw
, and select JSON
from the dropdown list to indicate the format of your data. Please take a look at the answers here and here for more details.
