REST Endpoints Error Logging Script | Dataford Interview Questions

Write a script that hits multiple REST endpoints and logs the errors.

Asked in the Coding test stage.

For deterministic grading, implement the error-processing portion using endpoint results produced by a mocked REST client. Each result is a dictionary with url, status, and optional error. Return one structured record for every failed request, where failures include HTTP status codes >= 400 and requests with a non-empty error. Also log each returned record with the logging module.

Input and Output

Implement log_endpoint_errors(results). Return records containing url, status, and error, preserving input order. Successful responses produce no record.

Constraints

1 <= results.length <= 10^4
Each result contains a non-empty string field named url
status is null or an integer from 100 through 599
error is absent or a string
Return records in the same order as their failed inputs

Function Signature

def log_endpoint_errors(results):
