Missing Required Field
The Missing Required Field analyzer detects function instances where a required input field has been left empty.
Every function has a set of parameters. Some of those are required, your action cannot execute correctly without them. If a required field has no value (neither a variable from scope nor a hard-coded value), this analyzer will flag it.
How to fix it
Open the function instance and fill in the missing required field. You can either type a value directly or pick a variable from your variable scope.
Severity
Major/Bug - the action will fail at runtime when it reaches this step.
