Node unable to be created with empty tag value

What happened?

I am deploying eks cluster with pulumi python.

Module versions:

• arpeggio-2.0.2
• attrs-23.2.0
• boto3-1.34.129
• botocore-1.34.129
• certifi-2024.6.2
• charset-normalizer-3.3.2
• dill-0.3.8
• grpcio-1.60.1
• idna-3.7
• jmespath-1.0.1
• parver-0.5
• protobuf-4.25.3
• pulumi-3.120.0
• pulumi-docker-4.5.4
• pulumi-kubernetes-4.13.1
• pulumi_aws-6.41.0
• pulumi_awsx-2.12.1
• pulumi_eks-2.7.1
• python-dateutil-2.9.0.post0
• pyyaml-6.0.1
• requests-2.32.3
• ruamel.yaml.clib-0.2.8
• ruamel_yaml-0.18.6
• s3transfer-0.10.1
• semver-2.13.0
• six-1.16.0
• typing-extensions-4.12.2

I am attaching tags to the resources, and one tag has empty string("") value. Pulumi python is unable to create the EKS Node wth empty string("") as tag value.

Example

cluster = eks.Cluster("example_cluster_name",
    vpc_id = example_vpc_id,
    name = example_eks_cluster_name,
    tags = {"tag1" : "value1","tag2" : "value2","tag3" : "value3","tag4" : ""},
    public_subnet_ids=example_public_subnets,
    private_subnet_ids=example_private_subnets,
    create_oidc_provider=True,
    node_associate_public_ip_address = False)

Output of pulumi about

• aws:cloudformation:Stack example-nodes creating (0s) @ updating.....

Hi @RagunathAnbarasu the issue you are reporting comes from AWS. They are validating to ensure tag values cannot be empty. Since this is expected behaviour of AWS, I don't think there is anything we can do on our side to address this - you'll need to update your tag values to not be empty. Please let me know if I'm overlooking something.
