[BUG]: github_release resource creates drift, leading to provider error

[simpl-sam]

Expected Behavior

When applying the github_release resource with the argument generate_release_notes set to true, the release would be created and subsequent plans to terraform plan would show the body value to now contain the generated release notes and the generate_release_notes flag is set to false.

Setting the body and generate_release_notes arguments in the Terraform template to match the delta, will cause a subsequent plan to report "no changes"

Actual Behavior

The delta is still being seen as a change, but not presenting what is different (might be tabs vs spaces or something like that)

Applying the changes produces a provider error

Terraform Version

v1.6.3

Affected Resource(s)

• github_release

Terraform Configuration Files

No response

Steps to Reproduce

• Create a release resource which generates release notes
• terraform apply
• backfill notes post-apply back into template
• terraform plan
• terraform apply

Debug Output

No response

Error: The terraform-provider-github_v5.42.0 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.

Operation failed: failed running terraform apply (exit 1)
