How do I get terraform plan to show me all of the deprecation warnings?

[grimm26]

In doing a plan I get this warning:

╷
│ Warning: Argument is deprecated
│
│   with module.test.aws_s3_bucket_object.lambda_s3_object,
│   on ../main.tf line 87, in resource "aws_s3_bucket_object" "lambda_s3_object":
│   87:   bucket   = local.deployment_bucket
│
│ Use the aws_s3_object resource instead
│
│ (and 3 more similar warnings elsewhere)

How do I get it to show me the 3 more similar warnings elsewhere?

Hi @grimm26,

If you run the validate command in JSON mode then you can see the underlying data that the UI is rendering, and thus see the full detail:

terraform validate -json

[grimm26]

plan and validate give me a different number of warnings

[nicolaj]

did you figure out a solution to this?

Hi @nicolaj,

I’m not the original poster but a similar answer to what I described should work for planning too: terraform plan -json replaces the human-oriented UI with a JSON stream, and that stream should include events representing the diagnostic messages, along with other events that correspond to other information that would normally be produced during the planning phase.
