Can the maximum string length for process parameters be increased?

When we invoke our AEM processes via REST endpoints - i.e. processes created in Adobe Workbench, we are getting an error if the string exceeds 2000 characters:

Invalid input. The maximum length of 2000 characters was exceeded.

Is there a way to increase the maximum allowed length?

For Json results, it will be the "max json results" at the default get servlet[1]

[1] http://<host>:<port>/system/console/configMgr/org.apache.sling.servlets.get.DefaultGetServlet

It is not recommended to send whole data in the query parameters rather in the body. Please try the same by sending the data in body.
