Pydantic with FastAPI: How to customise the message for "422 Unprocessable Entity" error?

Question

When sending wrong parameters, how can I customise the "422 Unprocessable Entity" error message to receive, instead of:

{"detail": [
{
"loc": [
. . . . . .
],
"msg": "field required",
"type": "value_error.missing"
}
]}

something more simple like this:

{"status": "failed", "error": "value_error.missing"}
