Missing Action Outputs
The Missing Action Outputs analyzer detects when you call another action that produces outputs, but you haven't mapped those outputs to variable names.
When a called action returns results, each output needs to be captured in a named variable so your logic can use it. If an expected output has no variable name configured, this analyzer flags it.
How to fix it
Open the function instance that calls the action and add variable names for each output in the outputs section.
Severity
Major/Bug - any step that tries to use the unmapped output will fail or receive nothing.
