Panic Output

https://gist.github.com/sudomateo/14662ec6cd8684cef2a8f6d6b9499649

Expected Behavior

The terraform apply command should have created the datadog_screenboard resource successfully.

Actual Behavior

The terraform apply command produced a panic as noted above.

Steps to Reproduce

1. Create main.tf with the content above.
2. Run terraform init to download the Datadog provider plugin.
3. Run terraform plan to verify the plan output.
4. Run terraform apply to apply the plan. Enter yes when prompted.
5. Note the crash.

Important Factoids

After testing with previous commits, it seems that this issue was introduced by commit 19ba2e52a2ee8218716157608b40a215c15d798c. However, you’ll have to build using commit bd8075f19b50ff62cc391c5238054dc390143eb9 if you want to compile the provider plugin successfully.

Also, even the acceptance tests are failing:
