Passing a JSON to a DMN table as input

BPMN & Modeling Discussion & Questions

Hello,

I have a process that receives the below JSON object as an input:

{ “variables”: {
“data”: {
“value”: “{\r\n "check":{\r\n "id":"62fa9904-e7ab-41cd-b1d2-d938160f0295",\r\n "session":"d3ac5e36-52fe-4844-990d-b9fc0557bfeb"}}”,
“type”: “Json”, “valueInfo”: {“objectTypeName”: “test”, “serializationDataFormat”: “application/json” }
},

Could you please help me to use it as an input in a DMN table from this process?

I tried with the following FEEL expression: JSON(data).prop(“check”).prop(“id”).stringValue() and set the type as String but I got the below error message:

{

"type": "FeelException",

"message": "FEEL/SCALA-01008 Error while evaluating expression: failed to parse expression 'JSON(data).prop(\"check\").prop(\"id\").stringValue()': Expected (StringIn(\"<=\", \">=\", \"<\", \">\", \"!=\", \"=\") | \"between\" | \"in\" | \"and\" | \"or\" | end-of-input):1:16, found \"(\\\"check\\\").\""

}

Thank you in advance for your help!

Hi @DianaArti :wave:

Try to use the following FEEL expression:

data.check.id

In FEEL, you can access the JSON properties directly instead of using the Camunda Spin API.

Does this help you?

Best regards,
Philipp

Hi Philipp!
Thank you for your help! It worked like a charm :slight_smile: I didn’t imagine the expression can be so straightforward and simple.
