Provider Crashing on Specific Tenant

[manderson202]

Hello, we are seeing the provider crash on one of our tenants. We are using the latest v0.30.0 version of the provider.

Describe the problem

After running a plan we get the following output:

╷

│   on main.tf line 74, in resource "auth0_client_grant" "user-management-app-client-grant":

Error: The terraform-provider-auth0_v0.30.0 plugin crashed!

This is always indicative of a bug within the plugin. It would be immensely
helpful if you could report the crash with the plugin's maintainers so that it
can be fixed. The output above should help diagnose the issue.

ERRO[0011] 1 error occurred:
	* exit status 1

What was the expected behavior?

The plan would complete without error.

Reproduction

I believe this is specific to our tenant as the same TF works fine in all of our other tenants except this one. I opened support request 00745742 to look more into the tenant-specific nature of the error and was told to open an issue here.

Environment

We are using v0.30.0 of the provider. We are using Terraform v1.1.2 run via Terragrunt v0.31.0

Hey @manderson202 thanks for raising this with us! 🙏🏻 The debug output provided above helped pinpoint the issue and I have a fix up within #140. Would you be able to help test this from your end before we merge it?

We have a make command to install the binary locally without going through the terraform registry you can run make install VERSION=0.30.1 and then update the provider version in your terraform config to v0.30.1. You need go installed locally tho brew install go on mac for example. Or you can install it with https://go.dev/doc/install.

We fixed this in https://github.com/auth0/terraform-provider-auth0/releases/tag/v0.30.1. It will be available shortly from the terraform registry. Thanks for your patience 🙏🏻

[manderson202]

Thank you @sergiughf ! I was able to test this with the local install and it seems to be working as expected. I'll reach out if I run into any other issues.

Really appreciate the quick turnaround!!
