JOSM Won't Upload (OSM Server Error)

General talk
1

When I use JOSM to download from OSM, I get the following error:

“No data found in this area.”

When I download from Overpass API, make changes then upload I get the following error:

The OSM Server ‘https://master.apis.dev.openstreetmap.org/api/0.6/’ does not know about an object you tried to read, update, or delete. Either the respective object does not exist on this server or you are using an invalid URL to access it. Please carefully check the server’s address ‘https://master.apis.dev.openstreetmap.org/api/0.6/’ for typos.

JOSM version 19439

Last change: 2025-09-01

Java Version 21.0.8

Ubuntu 24.04.3 LTS

That API url is for the developer sandbox which if it has any data at all it is in general random test data.

PS: and that isn’t the Overpass API either.

Here is the tab which allows me to download the data:

Overpass

I did not modify the URL. I downloaded a new version of JOSM.

How do I fix it?

Settings -> OSM Server -> [x] Use the default OSM server URL (https://api.openstreetmap.org/api)

5

Edit → Preferences → OSM Server should roughly look like

PS: the title of your post says “Upload” the post is talking about download … Overpass is read only so will naturally not work for uploads.

The post started because of the error encountered while trying to upload. I added more information, including the error encountered while downloading.

I fixed the URL, according to the information above. I downloaded, made edits and uploaded. It now works!

Thanks!
