Notes and Constraints

• Each function can have a maximum of 20 tags.
• If your organization has configured tag policies for FunctionGraph, add tags to functions based on the policies. If a tag does not comply with the tag policies, function creation may fail. Contact your administrator to learn more about tag policies.
