Apikey parameter is not recognized when passing multiple querystring parameters

In my env i’ve setup key-auth plugin on route with path /route/path .

When testing http://localhost:8001/route/path/additional/path/to/file.csv?apikey=someapikey Kong successfully upstreams request.

But when i do call http://localhost:8001/route/path/additional/path/to/file.csv?parameter=value&apikey=someapikey Kong tells that “No API key found in request” and never upstreams request.

Does anyone have a clue why Kong cant recognize ‘apikey’ when multiple paramteres are passed in url?
