Malformed response when trying to validate address

[shachibista]

When trying to validate an address:

curl -v "https://papapi.se/json/?token=<TOKEN>&v=sdf|sdf|sdf|sdf" (address is clearly invalid)

The response is:

{"api":{"name":"PAP-API","url":"HTTPS://WWW.PAPAPI.SE/","version":"1.22","encoding":"UTF-8"},"result":{"address":{"street":"SDF","number":"sdf","zipcode":"sdf","city":"SDF"},"status":{"code":"100","description_sv":"KORREKT ANGIVEN ADRESS","description_en":"CORRECT SPECIFIED ADDRESS"}}}

Note two issues:

1. The JSON response is tainted by PHP warning
2. The response says the address is "CORRECT SPECIFIED ADDRESS" even though it is clearly incorrect.
