[Bug]: Eventbridge rule changed from enabled to disabled without showing in Terraform plan

[shalev123d]

Terraform Core Version

1.3.6

AWS Provider Version

5.31.0

Affected Resource(s)

aws_cloudwatch_event_rule

Expected Behavior

We have the rule with ignore_changes on is_enabled, which is set to disabled in the code, but the rule is enabled in AWS. I tried to change the rule's event pattern, and the terraform plan output showed only the expected change is about to occur (pattern change) but also changed the rule from enabled with disabled, even though it's in ignore_changes.

TF Plan output -

 # aws_cloudwatch_event_rule.rule will be updated in-place
  ~ resource "aws_cloudwatch_event_rule" "rule" {
      ~ event_pattern  = jsonencode(
          ~ {
              ~ detail      = {
                  ~ object = {
                      + size = [
                          + {
                              + numeric = [
                                  + ">",
                                  + 0,
                                ]
                            },
                        ]
                        # (1 unchanged element hidden)
                    }
                    # (1 unchanged element hidden)
                }
                # (2 unchanged elements hidden)
            }
        )
        id             = "my-rule"
        name           = "my-rule"
        tags           = {}
        # (5 unchanged attributes hidden)
    }

Actual Behavior

The rule changed from enabled to disabled

Critical update - after adjusting to the "state" parameter, it is still ignoring the "ignore_changes" and it has disabled the eventbridge rules (enabled manually, disabled in HCL)

Hi, we're currently preventing ALL updates to our production Terraform managed event rules due to this issue. Would highly appreciate your attention here :)

Hi, we're currently facing the same issue. Are there any updates?
