Null Pointer

The Null Pointer analyzer detects when a variable that may be null is used in a step without checking for null first.

Some steps produce a result that can be null, for example, a Fetch record by ID step returns null when no matching record is found. If a later step uses a field on that result (e.g. {USER.email}) without first checking whether the variable exists, your action will crash at runtime when the record is missing.

How to fix it

Add a conditional on the edge between the step that produces the variable and the step that uses it. Check that the variable is not null before continuing.

This way, the step that uses {USER.email} is only reached when USER actually has a value.

Severity

Major/Bug - this will cause your action to fail at runtime whenever the variable is null.
