L3 - Default Description
When via POST /variable-instance the returned variables does not provide an activityInstanceId, for example like this:
[{
"type": "Long",
"value": 123456,
"valueInfo": {
},
"id": "def",
"name": "aVariable",
"processInstanceId": "abc",
"executionId": "xyz",
"caseInstanceId": null,
"caseExecutionId": null,
"taskId": null,
"activityInstanceId": null,
"errorMessage": null
}]
then the following exception is thrown:
angular.js:9778 TypeError: Cannot read property 'id' of undefined at http://localhost:8080/camunda/api/cockpit/plugin/base/static/app/plugin.js:2:693 at Array.map (native) at http://localhost:8080/camunda/api/cockpit/plugin/base/static/app/plugin.js:2:424 at http://localhost:8080/camunda/app/cockpit/scripts/deps.js:5:8462 at c (http://localhost:8080/camunda/app/cockpit/scripts/deps.js:5:22813) at c (http://localhost:8080/camunda/app/cockpit/scripts/deps.js:5:22813) at http://localhost:8080/camunda/app/cockpit/scripts/deps.js:5:23490 at c.$eval (http://localhost:8080/camunda/app/cockpit/scripts/deps.js:5:28557) at c.$digest (http://localhost:8080/camunda/app/cockpit/scripts/deps.js:5:27087) at c.$apply (http://localhost:8080/camunda/app/cockpit/scripts/deps.js:5:28876)
Expected behavior:
The variables are shown in tab even if no activityInstanceId is provided
Hints:
The var instance is undefined in such a case, see
