Groovy script not performing the bursting definition job

Summary: I need to perform a bursting definition job in NR for which the Groovy script has been developed in the EPM planning. We have established the connection for the NR as well. However, the script is launching without any errors, but the bursting definition job has not been performed. I've attached the code for reference.

Content (required): I got the ID through the postman.

Since I wanted to know the output of the code, I've added a println line after the first line. So when I went and checked the job status, it displayed the following message: oracle.epm.api.model.rest.HttpResponse@5bee91c1
