AWS CLI cloudwatch log subscription without any filter pattern

Question

I'm trying to get logs from an application running in AWS, including all logs without any filter pattern:

aws logs put-subscription-filter --log-group-name "abc-loggroup" --filter-name "Destination" --filter-pattern "" --destination-arn "arn:test" --role-arn "arn:role"

getting following error - aws: error: argument --filter-pattern: expected one argument

Tried running the command without "--filter-name" parameter it failed.

How can I run this command without any filter pattern
