Historic Process Variable Not Being Returned

Hi, I am using activiti 5.15.1 with a postgresql db. When I use the rest api to query historic process variables and I am getting all process variables but one back: https://blqadb3.ls.cbn/restactiviti/service/history/historic-variable-instances?processInstanceId=701{"data":[{"id":"718","processInst

The even weirder part is if I ask for the variable by name I do get the value I am looking for:

https://blqadb3.ls.cbn/restactiviti/service/history/historic-variable-instances?variableName=serialNumber&processInstanceId=701
<code>
{"data":[{"id":"727","processInstanceId":"701","processInstanceUrl":"https://blqadb3.ls.cbn/restactiviti/service/history/historic-process-instances/701','taskId':null,'variable':{'name':'serialNumber','type':'string','value':'A','scope':null}}],"total":1,"start":0,"sort":"variableName","order":"asc","size":1}
</code>

In the end this is what I really need but I am still confused as to why this variable isn't returned in the complete list.

This confuses me too … there is no filtering being done in the query!

You could always enhance the log level on the engine side, and see which SQL query is being executed for that call.

I was having the same problem and found this topic. However, I was trying to get binary data and I found the solution in the Alfresco documentation: http://docs.alfresco.com/activiti/topics/getTheBinaryDataForAHistoricProcessInstanceVariable.html

Solution: GET history/historic-process-instances/{processInstanceId}/variables/{variableName}/data
