[BUG]: Cannot disable squash merge because of 422 Validation Failed

[ecolomer]

Expected Behavior

When I run a terraform plan for github_repository resources, which have allow_squash_merge set to false, I should not see any values for squash_merge_commit_message and squash_merge_commit_title.

Actual Behavior

The provider code sets a default for squash_merge_commit_message and squash_merge_commit_title, even when allow_squash_merge is set to false.

And then, when I run a terraform apply, I get the following error:

Error: PATCH https://api.github.com/repos/xxxx/xxxx: 422 Validation Failed [{Resource:Repository Field:merge_commit_allowed Code:invalid Message:Sorry, you need to allow the squash merge strategy in order to set the default squash commit message title or message. (no_squash_merge_strategy)}]

Terraform Version

Terraform v1.2.9 on darwin_arm64 + provider registry.terraform.io/hashicorp/tls v4.0.5 + provider registry.terraform.io/integrations/github v5.45.0

Affected Resource(s)

• github_repository
