Hi,  
Whenever I try to get a list of POIs, ordered by category, it results in a 500 internal server error. When I use [https://api.openrouteservice.org/pois](https://api.openrouteservice.org/pois) to post the following:  
{“request”: “pois”,“geometry”: {“geojson”: {“type”: “Point”,“coordinates”: [5.058349000000001,52.647953]},“buffer”:1000},“limit”:100,“filters”: {“category\_group\_ids”:[420]},“sortby”:“category”}

which results in  
{“code”:500,“message”:“Internal server error”}

If I comment out the sortby, it works fine. Since this is correct according to the docs, I am assuming this is a bug?

Just now noticed that I should probably round down the coordinates, 6 decimals or more is a little over the top: but it should not cause an HTTP-500 I think.

TIA,  
Stefan

Hey,

thanks for noticing 🙂  
This does indeed look like a bug ☹ I have submitted [an issue](https://github.com/GIScience/openpoiservice/issues/120) to the respective repository. You can follow the discussion and progress on this over there.

Best regards

Thank you!

I noticed it because I was looking for shops in a town, and thought to myself: wow, that is a long list, it would be convenient if I could order that by category - that would save me scrolling.  
My current workaround is to allow a finer selection of shops, and not request the entire category group. And of course I could sort myself on the client side, but that became a bit slow.

Cheers,  
Stefan

Yes! Thank you, that was quick 🙂  
Just did a quick test, and that looks great. Now I can add a header to the list of results using the category, which makes it a little bit easier to navigate the results list if there are a lot of results.

Thank you again! Love it, one more item for which I won’t use that maps-product from that waaay to big search engine monstrosity anymore 😉 😁
