[Bug]: aws_bedrock_guardrail_version resource producing inconsistent result

[pursachi]

Terraform Core Version

1.6.0

AWS Provider Version

5.74

Affected Resource(s)

aws_bedrock_guardrail_version

Expected Behavior

It should not show error if there is already a guardrail version available.

Actual Behavior

aws_bedrock_guardrail_version resource shows inconsistent result after apply. It creates a guardrail version in the first run, in the subsequent runs it errors out with the below error message:

Error: Provider produced inconsistent result after apply
<span>
When applying changes to aws_bedrockagent_agent, provider "provider[\"registry.terraform.io/hashicorp/aws\"]" produced an unexpected new value: .guardrail_configuration: was
cty.ListVal([]cty.Value{cty.ObjectVal(map[string]cty.Value{"guardrail_identifier":cty.StringVal("<guardrail_id>"),
"guardrail_version":cty.StringVal("3")})}), but now null.
