Test failures are unrelated to my fix - test looked like it updated grant_types ok.

Hi @domg123, thanks for submitting this! Looking at the errors, it might be that d.Set("grant_types", c.GrantTypes) didn't work as expected.

This error message suggests that the grant_types are being set to an empty array after the value is being read back from Auth0:

grant_types.#: "4" => "0"

Sometimes the Auth0 API doesn't return all the values from a resource, unless you explicitly request them. We might need to update the Auth0 SDK for this to work.

Ok. So I've pulled your branch to verify my hypothesis, but it turns out I was wrong :)

The solution was much easier, it was related to grant_types being defined as optional, but not as computed. In this case grant_types will be generated if none is set (by Auth0).

TLDR; we just need a Comuted: true to the schema and it should be good to go!

Thanks for taking a look! I've added Computed.
