Scope
Any
Is Null checks one context variable and continues on true when the value is missing or null. Anything else (including empty text) takes the false outlet.
Use Is Not Null for the inverse. Use Exists when a null value should still count as present. Use Is Empty for empty text, lists, or objects.
Configure
| Setting | Description |
|---|---|
| Variable | Context path to test (args.*, pipe.*, named variables, and so on) |
If Variable is not set, the run takes the false path.
Handles
| Handle | Role |
|---|---|
| In (target) | Incoming connection |
| Out (source) | Continues when the value is missing or null |
| False | Continues when the value is present (including empty text) |
Connect both outlets if every path should keep running. An unconnected outlet ends that branch.
Pipe schema
The next block reads this on the data pipe (pipe.value).
| Field | Type | Description |
|---|---|---|
| Result | boolean | true when the value is missing or null |
Use case
- Guard a later block that cannot run without a value (optional argument, optional lookup).
- After a table or API step, branch when a field came back null versus a real value.
- Pair with Is Not Null when you only need this one test instead of a full Condition query.
