Hello, I'm trying to define a cloudwatch alarm and I'm getting TS error

TS2322: Type 'Output<string | undefined>' is not assignable to type 'Input<string>'

Because

dimmensions

is defined as

/**
     * The dimensions for this metric.  For the list of available dimensions see the AWS documentation [here](<http://docs.aws.amazon.com/AmazonCloudWatch/latest/DeveloperGuide/CW_Support_For_AWS.html>).
     */
    dimensions?: pulumi.Input<{
        [key: string]: pulumi.Input<string>;
    }>;

Therefore I cannot use like this:

new aws.cloudwatch.MetricAlarm(
      this.rcName('CpuHigh'),
      {
       ...
        dimensions: {
          ClusterName: this.cluster.clusterName!,
          ServiceName: this.service.name
        }

      }
    )

I noticed a similar issue here: https://github.com/pulumi/pulumi-aws/pull/414 Is there any workaround for that?

What happens if you remove the

!

from the end of

clusterName

?

nothing

I believe what you are running into here is the same issue tracked in https://github.com/pulumi/pulumi/issues/6175. Note that this actually works fine in Node.js, just the TypeScript types don't allow it - so you can just cast to

any

and it will work. But there is also an improvement at the TypeScript layer being pursued in https://github.com/pulumi/pulumi/pull/6323 which would make this work without any need for workarounds.
