Hi all, We have implemented Open Street Map and It works great though. We are facing some challenges while accessing Open Street Map API from our endpoint. The error is as follows: CORS Error Access to XMLHttpRequest at 'https://nominatim.openstreetmap.org/search?format=json&q=vvvvv&limit=4' from origin 'http://localhost:4200' has been blocked by CORS policy: Request header field authorization is not allowed by Access-Control-Allow-Headers in preflight response. How can we fix this issue urgently ? Any help will be appreciated Thanks in advance asked 02 Aug '23, 08:28  SSD241993 edited 02 Aug '23, 08:28 |

While SomeoneElse pointed out the technical problem you should be aware that the nominatim.openstreetmap.org URL you currently use points to a demo service run by volunteers that can be down anytime and should not be used in production, esp. if something is "urgently". If you need a reliable service than you should look out for providers offering geocoding apis as a service or install nominatim yourself. Let's at least hope that you have read and adhere the usage policy that can be found here: https://operations.osmfoundation.org/policies/nominatim/ answered 02 Aug '23, 12:42  Spiekerooger |
