I am using cdk Aspects and I can see that the statement is being printed out from the visit method. However, when I try to add a Tag to each resource within my stack, nothing happens.

This is the line I have in my app.py.

cdk.Aspects.of(my_stack).add(TagsAddingAspect())

This is my aspect.py class.

import jsii
from aws_cdk import (
    IAspect, Tag, Tags
)
 
 

@jsii.implements(IAspect)
class TagsAddingAspect:
    def visit(self, node):
        print(f'{node.node.path} - {node.__class__.__name__}') # This gets printed so I know am definitely hitting the visit function for each resource.
        
        #Tags.of(node).add('aspect_test_tag', 'tag1')
        Tag('aspect_test_tag', 'tag1').visit(node)

I tried both options above to create a tag, but neither resulted in the tags being created in the stacks resources. The documentation indicates that either should work.

https://docs.aws.amazon.com/cdk/v2/guide/tagging.html

There may be a gap in my understanding… If someone could point me in the right direction, I’d appreciate it! Thanks.
