I keep experience ACCESS DENIED issue

Hi AWS, I already build a policy for my test user and also assign the policy to it, but when I trying to list the dynamodb table, always show next error: An error occurred (AccessDeniedException) when calling the ListTables operation: User: arn:aws:iam::055058096726:user/test is not authorized to perform: dynamodb:ListTables on resource: arn:aws:dynamodb:us-west-2:055058096726:table/* because no permissions boundary allows the dynamodb:ListTables action
