Hello.
Have you setup the environment variables?
Because your POST request is without appropriate domain

Hey @duedares-rvj, thanks for the suggestion.
No, I hadn't set up the environment variables and that was indeed the problem.

Should the provider give a better error message when this happens? Seems like a common enough issue, in this case with my configuration (I use a separate layer for credentials, which was not configured correctly).

@VenelinMartinov Hello again.
I'm really sorry if the error reporting was not adequate. Although, we have tried to best highlight the configuration setup as the very first step:
https://registry.terraform.io/providers/auth0/auth0/latest/docs

Let us know if there is anything further that we can add to improve the experience.
Thank you.

Hey @duedares-rvj thanks for the response!

Would it make sense for the provider itself to check that it is configured correctly and print an error message if not?

In my case, I was fully aware of he need to configure it but due to a type it was not configured correctly.

@VenelinMartinov I have added an explicit check for this. Hope that helps. Thanks.
