[olivia-dataskeptics]

Terraform Core Version

1.5.7

AWS Provider Version

2.7.9, 5.16.0

Affected Resource(s)

aws_batch_job_queue

Expected Behavior

Terraform apply should complete.

Actual Behavior

Provider produced inconsistent results after apply.

Relevant Error/Panic Output Snippet

│ Error: Provider produced inconsistent result after apply
│ 
│ When applying changes to aws_batch_job_queue.simple_flask_app_job_queue, provider
│ "provider[\"registry.terraform.io/hashicorp/aws\"]" produced an unexpected new value:
│ .compute_environments[0]: was cty.StringVal("flask-app-compute-env"), but now
│ cty.StringVal("arn:aws:batch:us-west-2:<id>:compute-environment/flask-app-compute-env").
│ 
│ This is a bug in the provider, which should be reported in the provider's own issue tracker.
