Hello, fellow Camunda enthusiasts!
I’m excited to dive into the world of Camunda with you all! I have a question regarding stringifying input variables of a map in Camunda Modeler, specifically when dealing with JSON.
Task: I need to convert a map’s input variables, which are in JSON format, into string (value of taxpayer in screenshot)
Hello my friend!
I like to use SpinJson’s S() method.
Take a look at the links below, which may help you, and with this you will be able to work with your object within camunda itself, accessing the properties through .prop().
I hope this helps.

Hi William, as always thank you for your response). Actually i whant to stringifye it in Camunda modeler. In this example I mean the value of map ${taxpayer}, will it be possible to do it ?
Have you tried using JSON.stringify() for what you need my bro?
I believe you can do something like:
${JSON.stringify(taxpayer)}
Try using this, and let me know if it worked and if this is what you needed.

it dose not worked
org.camunda.bpm.engine.ProcessEngineException: Unknown property used in expression: ${JSON.stringify(taxpayer)}. Cause: Cannot resolve identifier 'JSON'

actually I solve it by creating intermediate script task and stringifying the JSON Object
Haaaa I had understood that you didn’t want to use Java and the ObjectMapper is part of the Jackson/Java lib.
I got it wrong.
I’m glad you made it!
