Unexisting Method Used
The Unexisting Method Used analyzer detects when an action contains a function instance that references a method that does not exist on the platform.
When a function instance points to a method key that is unknown, the action will fail at runtime because there is nothing to execute.
How to fix it
Open the flagged function instance and replace it with a valid method from the available functions list.
Severity
Bug - the action will fail at runtime because the referenced method does not exist.
