Hello, I'm struggling to understand how to inject the standard Golang string representation of an iam role ARN created by pulumi into an ecs container definition. I've tried the following (and many other approaches) but have not been successful. Is anyone able to provide any insight on this?

executionRoleArn := executionRole.Arn.ApplyT(func(arn string) string {
		return arn
	})

// Container Definition
	containerDefinitionJSON, err := json.Marshal([]interface{}{
		map[string]interface{}{
			"name":             "workerr",
			"image":            "<http://1234567890.dkr.ecr.us-east-2.amazonaws.com/worker:latest|1234567890.dkr.ecr.us-east-2.amazonaws.com/worker:latest>",
			"cpu":              250,
			"essential":        true,
			"memory":           256,
			"executionRoleArn": executionRoleArn,

I've not been able to get past the following error

error: an unhandled error occurred: program failed:
    1 error occurred:
        * json: error calling MarshalJSON for type pulumi.StringOutput: Outputs can not be marshaled to JSON

I’m still fairly new at this, but basically, you can’t get your ARN as a

string

outside of the

ApplyT

. If you need to use it as such, you need to do the work inside the

Apply

function. If your container definition is ultimately going to another Pulumi resource, you probably want to just keep passing everything around as Pulumi outputs and not force resolution to the underlying type.

You should be able to change

json.Marshal

to

pulumi.JSONMarshal
