hi, I have a weird issue with ignoreChanges, there's a resource in a ComponentResource class:

const vpc = new aws.ec2.Vpc(
      vpcName,
      {
        cidrBlock: cidrBlock,
        enableDnsHostnames: true,
        enableDnsSupport: true,
        tags: Object.assign(
          {
            Name: vpcName
          },
          args.resourceTags
        )
      },
      { parent: this }
    )

if I change this to

const vpc = new aws.ec2.Vpc(
      vpcName,
      {
        cidrBlock: cidrBlock,
        enableDnsHostnames: true,
        enableDnsSupport: true,
        tags: {
          Name: vpcName
        }
      },
      { parent: this, ignoreChanges: ['tags'] }
    )

and trying to update the stack, I got an error:

aws:ec2:Vpc (dlv-sbx-vpc):
    error: aws:ec2/vpc:Vpc resource 'dlv-sbx-vpc' has a problem: tags (kubernetes): '' expected type 'string', got unconvertible type 'map[string]interface {}'
 
  pulumi:pulumi:Stack (dliver-dlv-sbx):
    error: Running program '/home/ncsibra/dev/prmrgt-infra/pulumi/dliver' failed with an unhandled exception:

This resource has a tag, added by EKS, something like

<http://kubernetes.io/cluster/dlv-sbx-cluster-eks-197239a|kubernetes.io/cluster/dlv-sbx-cluster-eks-197239a>: shared

, this tag not exist in pulumi code, because vpc created first, then EKS, so unable to add it from pulumi, but after a refresh, pulumi tries to remove that, but that would cause problems with resources handled by kubernetes. So I tried to add ignoreChanges, but looks like it want to do something with the tags anyway and unable to parse it.

mmm I forget who led this work. Was it @bitter-oil-46081?

It was @white-balloon-205.

@cold-coat-35200 Could you open an issue in https://github.com/pulumi/pulumi-aws? I'll look into it.

done, https://github.com/pulumi/pulumi-aws/issues/553, thanks @white-balloon-205
