How can I update the option propagateTags on an already created ECS service

Question

I need to tag all the existing and coming task definitions for a given ECS service. The issue is that I realized that the "PropagateTags" property of the service is set to "NONE" and the tasks definitions do not have the required tags. I attempted to update that property in the console first, but it was not possible. Then, I used the next command:

aws ecs update-service --cluster my-cluster --service my-service --propagateTags  SERVICE --profile "my-profile"

But that didn't work either, because the argument "propagateTags" was not recognized.

My last attempt was using boto3 (API) using the next script:

import boto3

session = boto3.Session(profile_name = 'my-profile', region_name = 'us-east-1')
    
ecs_cluster= 'my-cluster'
ecs_service= 'my-service'

ecs_client=boto3.client('ecs')

response = ecs_client.update_service(
    cluster=ecs_cluster,
    service=ecs_service,
    propagateTags='SERVICE'
)

But, guess what? That didn't work because the API call didn't recognize the tags argument.

Traceback (most recent call last):
  File "./ecs_propagatetags.py", line 16, in <module>

Unknown parameter in input: "propagateTags", must be one of: cluster, service, desiredCount, taskDefinition, capacityProviderStrategy, deploymentConfiguration, networkConfiguration, placementConstraints, placementStrategy, platformVersion, forceNewDeployment, healthCheckGracePeriodSeconds, enableExecuteCommand

Any ideas on how I can resolve the issue? Recreating the service is the very last option.
