Problem: Complete the implementation of a function called handle_error that serves as an error handler within a Falcon web application. The function should accept four parameters: the request and response objects, an exception instance, and a dictionary of additional parameters. Its primary responsibilities include extracting contextual information from the request—such as the request path—and combining this with the error details provided by the exception, then using these pieces of information to set the response's media attribute to a JSON object that contains an error message along with supplementary details (including the request path and any additional parameters). Additionally, the function must update the HTTP status of the response to signal an internal server error (HTTP 500).
