How can we convert that input variable to a JSON object hence we can iterate it and do the required operations in camunda script task?

Hello my friend!

If you look for the variable with

var insertList = execution.getVariable("insertList");

After this, transform the variable into a Json String as follows:

var jsonString = JSON.stringify(insertList);

And finally parse the Json string to a Json object:

JSON.parse(jsonString);

Doesn’t work for you?

Hi friend!.

We have list size of 20 elements.

When using → var insertList = execution.getVariable(‘insertList’); we are getting error in Camunda that varchar(4000) too long.

The size which we are sending is around 10000.

Thanks
Santosh.
