Summary
Acunetix 360 detected that the applicaton does not handle unhandled rejection.
The unhandledRejection event is emitted whenever a Promise is rejected and no error handler is attached to the promise within a turn of the event loop. By default, Node.js handles such exceptions by printing the stack trace to stderr and exiting with code 1. It's recommended to implement a handler function for this unhandled event.
Impact
An attacker can force the web application to terminate by generating an exception.
Actions To Take
Your web application should implement a handler function for the unhandledRejection event.
