Is Null
Check if a value is null or empty.
Returns true when the connected value is null or empty.
Inputs
- Value — T. Uses the value to test for absence. The node checks for a null reference, an empty string, or the literal string null, and it does not treat other falsy-looking values as null.
Outputs
- Result — Boolean. Represents whether the input is considered null by the node. True means the value was null, empty, or the string null, and false means it had some other value.
Example use cases
Require a field
Feed a field into Is Null and branch to a comment asking the reporter to fill it in when the result is true.
