Use Camunda Spin in Modeler?

[unkown]

So now it worked…
I am not realy sure what i did wrong.
But it created a new BPMN like the old one. created a Script Task to convert the input String from the API
=> S(product) and the Sequence Flow got the expression:

${product.prop("meta").prop("x").numberValue()==2}

My Input (REST API POST) look like this:

{
	"variables":
	{
		"product":
		{
			"value":"{\"meta\":{\"category\":2}}","type":"String"
		}
	}
}

No Exceptions and the right output by my workflow.

thanks for all your helpful suggestions
