caseInstanceVariables

Camunda 7 Topics Discussion & Questions
1

suppose I start a task with
{
“variables”: {

		"amount": {
			"value":555,
			"type":"long"
 		},
		"class": {
			"value":"3000",
			"type":"string"
		}
	}
}

Now I query with: http://localhost:8080/engine-rest/task?caseInstanceVariables=class_eq_3000

Will this return the Tasks associated with the value? I am getting an empty set.

Hey @lenny_h,

caseInstanceVariables are related to CMMN. You want probably to query for taskVariables.

taskvariables did not work

http://localhost:8080/engine-rest/task?processVariables=serial_eq_3000
worked. ( I may have serial in some form fields)
But I tried another variable (amount) that is a long, and got no result. Does it only work for strings?

As described in the docs, for the GET Request, Values are always treated as String objects on server side.

You can use the POST equivalent instead: https://docs.camunda.org/manual/latest/reference/rest/task/post-query/
