boto3 s3 bucket tagging – Amazon web services

I’m getting access error while tagging a bucket. Please note that the role I’m using has s3 full access.
The code works fine till this point-

for bucket in s3.buckets.all():
            s3_bucket = bucket
            s3_bucket_name = s3_bucket.name
            try:
                response = s3_client.get_bucket_tagging(Bucket=s3_bucket_name)
                print(response)
            except ClientError:
                print (s3_bucket_name, "does not have tags")

but after adding putTag code, it gives error even for GetBucketTagging operation.
This is my final code:

for bucket in s3.buckets.all():
            s3_bucket = bucket
            s3_bucket_name = s3_bucket.name
            try:
                response = s3_client.get_bucket_tagging(Bucket=s3_bucket_name)
                print(response)
                
            except ClientError:
                print (s3_bucket_name, "does not have tags")
                bucket_tagging = s3.BucketTagging(s3_bucket_name)
                response = bucket_tagging.put(
                 Tagging={
                      'TagSet': [
                        {
                            'Key': 'pcs:name',
                            'Value': s3_bucket_name
                        },
                      ]
                    },
                )

The error I’m getting is-

botocore.exceptions.ClientError: An error occurred (AccessDenied) when calling the GetBucketTagging operation: Access Denied

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "tagging.py", line 91, in <module>
    tagging()
  File "tagging.py", line 71, in tagging

    raise error_class(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (AccessDenied) when calling the PutBucketTagging operation: Access Denied

am I passing the tag parameters wrong? Got this from Boto3 documentation itself

    I couldn't find a way to catch the exception, however, this worked for me:

    tagging_client = boto3.client('resourcegroupstaggingapi')
s3 = boto3.resource('s3')
s3_client = boto3.client('s3')
for bucket in s3.buckets.all():
     s3_bucket = bucket
     s3_bucket_name = s3_bucket.name
     bucket_tagging = s3.BucketTagging(s3_bucket_name)
     try:
        response = s3_client.get_bucket_tagging(Bucket=s3_bucket_name)
        a = response
     except ClientError:
        response = tagging_client.tag_resources(
        ResourceARNList=[
            "arn:aws:s3:::" + bucket.name
        ],
        Tags={
            'pcs:name': bucket.name
        }
      )

    pls note that you'll need the additional "resource tagging" policy attached to your role. Hope this helps. Cheers.

    I took out the try sections and ran this version of your code:

    import boto3

s3_resource = boto3.resource('s3')

bucket_tagging = s3_resource.BucketTagging('my-bucket-name')
response = bucket_tagging.put(
        Tagging={
            'TagSet': [
            {
                'Key': 'pcs:name',
                'Value': 'stackoverflow'
            },
            ]
        },
    )

    It worked fine:

    [Amazon S3 bucket tags

    Therefore, there must be something else that is causing your request to fail. You might want to check AWS CloudTrail to see if there is a hint as to why the request was denied.

    "get_bucket_tagging" throws NoSuchTagSet when there are no tags. for testing create a tag first before run test or Catch the exception and create tags.
