The /pois endpoint returns HTTP 200 with an empty features array for both bbox and Point+buffer queries in dense city centers (e.g., Heidelberg, Berlin, Paris) and includes an invalid bbox: [NaN, NaN, NaN, NaN] in the response body. Reproducible via API console and client. Example request:
{"request":"pois","geometry":{"geojson":{"type":"Point","coordinates":[8.6821,49.4106]},"buffer":1500},"limit":50}
Example response (truncated):
{"type":"FeatureCollection","bbox":[NaN,NaN,NaN,NaN],"features":[],"information":{...}}
Looks like a backend regression in POI search and/or bbox generation.
