Problem Description

The dependency phin@2.9.1 is deprecated and is marked as a vulnerability.

Solution Description

Updated phin to a non-deprecated version, 3.7.1.
The phin function no longer accepts a callback function, it returns an object of type Promise<http.serverResponse>, updated the call to await this function call and only pass in opt. The result is passed into a refactored version of handleData.
