eks-blueprint : Error removing tag(s) from EKS cluster.

[narmada-chittem]

Describe the bug

Hello There!!

I’m facing an issue while removing tag(s) for an eks cluster.

Example code showing the tags being passed to the cluster provider -

return new FargateClusterProvider({
      version: kubernetesVersion,
      clusterName: this.props.clusterName,
      fargateProfiles: this.getFargateProfiles(),
      tags: this.props.tags,
      vpcSubnets: getFargatePrivateAndPublicSubnetSelection(this.props.vpc),
    });

Expected Behavior

We should be able to remove tags from the cluster.

Current Behavior

Problem:
I have an eks cluster with the following tags -

{
“tag1”: “tag1”,
“tag2”:”tag2”,
“tag3”:”tag3”,
“tag4”:”tag4”,
“tag5”:”tag5”,
“tag6”:”tag6”
}

When I try to remove a tag lets say “tag6”, my this.props.tags object looks like -

{
“tag1”: “tag1”,
“tag2”:”tag2”,
“tag3”:”tag3”,
“tag4”:”tag4”,
“tag5”:”tag5”,
}

While deploying I get the following error -

" at async tB.onUpdate (/var/task/index.js:63:10564)"
]
}

The error shows that empty tags are being passed but that is not the case. The tags are being passed correctly but this issue comes only when I do not pass all the tags that are already present on the cluster as mentioned in the above example.

Adding a new tag do not cause any issue -

{
“tag1”:“tag1”,
“tag2”:”tag2”,
“tag3”:”tag3”,
“tag4”:”tag4”,
“tag5”:”tag5”,
“tag6”:”tag6”,
“tag7”:”tag7”,
}

Passing a completely new set of tags does not cause any issue either. The existing tags get removed and the new tags get added.

{
“tag8”:“tag8”,
“tag9”:”tag9”,
}

Reproduction Steps

A. Create a cluster with some tags

const existingTags = {
“tag1”: “tag1”,
“tag2”:”tag2”,
“tag3”:”tag3”,
“tag4”:”tag4”,
“tag5”:”tag5”,
“tag6”:”tag6”
}
return new FargateClusterProvider({
      version: kubernetesVersion,
      clusterName: this.props.clusterName,
      fargateProfiles: this.getFargateProfiles(),
      tags: existingTags,
      vpcSubnets: getFargatePrivateAndPublicSubnetSelection(this.props.vpc),
    });

B. Remove a tag and redeploy the app

const updatedTags = {
“tag1”: “tag1”,
“tag2”:”tag2”,
“tag3”:”tag3”,
“tag4”:”tag4”,
“tag5”:”tag5”,
}
return new FargateClusterProvider({
      version: kubernetesVersion,
      clusterName: this.props.clusterName,
      fargateProfiles: this.getFargateProfiles(),
      tags: updatedTags,
      vpcSubnets: getFargatePrivateAndPublicSubnetSelection(this.props.vpc),
    });
