@stefangreim, which version of this provider are you using? I believe this issue has been resolved. I've added a test case to client grants and I can submit empty scopes normally.

[stefangreim]

@alexkappa v0.4.2
I found out the following: To create the client_grant, I have to use a non-empty scope. After the client_grant has been created, I can do an update with scope = []. So, create doesn't work, update works.
I checked when the last change in the code was done and the last version was built. I assumed that this change was already included.

I can confirm that a terraform import of an auth0_client_grant with scope = [] works as expected, and can also corroborate the behavior that @stefangreim observed.

Terraform v0.12.19
+ provider.auth0 v0.4.0

I am confident the issue is resolved with #162. Feel free to try v0.4.3 and let me know if all is well.

[stefangreim]

The error is resolved now. The grant works as expected.
Thanks!
