Error "Grant type 'password' not allowed for the client." for Resource Owner Password flow

I’m getting a simliar but not exact issue. on /ro i’m sending a request with grant type ‘password’ but i keep getting back:

{ “error”: “unauthorized_client”,
“error_description”: “Grant type
http://auth0.com/oauth/legacy/grant-type/ro
not allowed for the client.” }

I’ve added those grant types you specify above, and i tried to add http://auth0.com/oauth/legacy/grant-type/ro but it responds with:

"message": "Invalid grant types: http://auth0.com/oauth/legacy/grant-type/ro"
