conditionThe condition that tells if the given value is filled (not empty).
True when the value pin is neither nil/missing nor the empty string. Everything else counts as NOT empty: 0, false, whitespace, empty arrays, and empty objects all output true.
is not empty outputs true when the value on its pin contains something. Here it checks a field read with get fields before a branch decides whether the flow continues, the classic guard against empty document fields.
Commonly used with
In production blueprints, this block is most often wired together with:
- get fields: feeds into this block. Gets the selected fields from the given object.
- branch: this block feeds into it.
- AND: this block feeds into it. operator for a set of boolean operands will be true if and only if all the operands are true.
- if: this block feeds into it. use mutations X or Y based on a condition.
- if: this block feeds into it. Conditional branching for values (if.. then.. else..). Selects which input value is passed through; it does not route flow.
- create: feeds into this block. Creates a new function that can be executed using the given name.
