List all services by User created Resource Tags

[eKuG]

Hey @davfaulk can you also tell me how to list all services by resource tags?
I'm getting this error:
botocore.exceptions.ClientError: An error occurred (AccessDeniedException) when calling the GetTagValues operation: User: arn:aws:sts::678258727640:assumed-role/aws-cost-explorer-report-CostExplorerReportLambdaI-129HLOI5OJI1V/CostExplorerReportLambda is not authorized to perform: tag:GetTagValuesTotal chart

Wrote this piece of code:
def getResourcetags(self): tags = {} restag = boto3.client('resourcegroupstaggingapi', region_name='ap-south-1') response = restag.get_tag_values( PaginationToken='string', Key='string' ) # while 'PaginationToken' in response and response['PaginationToken']: # token = response['PaginationToken'] # response = restag.get_resources(ResourcesPerPage=50, PaginationToken=token) for response in response_iterator: for res in response['tags']: tags[res['Values']] = res return tags
