geonames cache query throws 500 error #323

Open elrayle opened 4 years ago

elrayle commented 4 years ago

Description

Authority: geonames_batch.jsp FAILING Query: New%20York%20%28NY%29 PASSING Query: New%20York%20NY

The %28 and/or %29 characters are the likely culprits. But it is preferred that this returns an empty set instead of error 500.

To reproduce

FAILING query

curl -L -D - -H 'Accept: application/n-triples' 'http://services.ld4l.org/ld4l_services/geonames_batch.jsp?query=New%20York%20%28NY%29&entity=AP&maxRecords=8&startRecord=1&lang=en'

PASSING query

curl -L -D - -H 'Accept: application/n-triples' 'http://services.ld4l.org/ld4l_services/geonames_batch.jsp?query=New%20York%20NY&entity=AP&maxRecords=8&startRecord=1&lang=en'

Expected

Either a set of matches or empty set.

Actual

Error for failing query:
