Keep getting this error and cannot seem to figure out what it is complaining about…

Hi @hpl002
When I export a BPMN that has an external service task in it, my bpmn:definitions line reads:

<bpmn:definitions xmlns:bpmn="http://www.omg.org/spec/BPMN/20100524/MODEL" xmlns:bpmndi="http://www.omg.org/spec/BPMN/20100524/DI" xmlns:dc="http://www.omg.org/spec/DD/20100524/DC" xmlns:camunda="http://camunda.org/schema/1.0/bpmn" xmlns:di="http://www.omg.org/spec/DD/20100524/DI" xmlns:modeler="http://camunda.org/schema/modeler/1.0" id="Definitions_1rec37n" targetNamespace="http://bpmn.io/schema/bpmn" exporter="Camunda Modeler" exporterVersion="4.9.0" modeler:executionPlatform="Camunda Platform" modeler:executionPlatformVersion="7.15.0">

I don’t see xmlns:camunda=“http://camunda.org/schema/1.0/bpmn” in your bpmn:definitions line, so the XML parser doesn’t know what to do with the camunda namespace.
