## Example request

```json
{
 "title": "Weather endpoint returns 500 error for London queries",
 "pokemon": "charizard",
 "description": "The weather API endpoint is consistently returning HTTP 500 Internal Server Error when attempting to query weather data for London. This occurs regardless of request format or parameters. Expected behavior: endpoint should return valid weather data or appropriate error code. Steps to reproduce: 1) Call GET /api/weather?location=London 2) Observe 500 response. Impact: Users cannot retrieve weather information for UK locations."
