Valhalla returning options are invalid error

I am trying to read the coordinates from kafka and do map matching on them. Kafka sends a single coordinate(lat,long) at a time. My map matching is unable to work on a single coordinate at a time using meili. If i pass bunch of coordinates directly in my program then it works. Is it a limitation that it cant treat single coordinate at a time and needs at least 2 coordinates ?

Yes, for map-matching you need minimum 2 coordinates (maybe even 3 or more, but likely only 2). Sounds like you might want to try /locate..

I also wouldn't call it a limitation. It's the same as you can't route with a single location..

Thanks for your reply. In that case , how can i use my kafka as a input to my map matching as it will always stream one record at a time ?

I have no idea what kafka is.. better suited for smth like stackoverflow IMO.
