I am working on Generated Task Forms, I am trying to apply true/false logic in exclusive gateway. If true, end process. If false, redirect to data correction task.

<bpmn:sequenceFlow id="SequenceFlow_180tuqy" name="Yes" sourceRef="ExclusiveGateway_1gplnrv" targetRef="EndEvent_16krmz0">
  <bpmn:conditionExpression xsi:type="bpmn:tFormalExpression">${approved}</bpmn:conditionExpression>
</bpmn:sequenceFlow>
<bpmn:sequenceFlow id="SequenceFlow_1" name="No" sourceRef="ExclusiveGateway_1gplnrv" targetRef="stock_management">
  <bpmn:conditionExpression xsi:type="bpmn:tFormalExpression">${!approved}</bpmn:conditionExpression>
</bpmn:sequenceFlow>

here ${approved} -> approved is the id of the boolean form fied, but it does not work.

what I need to mention in bpmn:conditionExpression?

First:
I´d like to ask if you write the BPMN-File yourself? Because there´s also a tool for it:
https://camunda.org/bpmn/tool/
Second:
On first sight I can´t see where there would be a problem. It looks ok to me. Often Camunda has problems with variables in conditions.
Try to write ${approved == true} instead of ${approved} and ${approved == false} instead of ${!approved}. If this doen´t work, maybe the problem lies elsewhere.
EDIT:
May you please explain what exactly happens, when quote "it does not work"?
