[HeinerSchaefer]

I have the same issue with JOSM v19555 and DirectUpload v36474.

Is there any workaround to get this fixed?

[stoecker]

I have no time to care for plugins, but I'll accept a patch when provided.

[HeinerSchaefer]

Because I have no idea about java, I can't help with this, sorry.
The only thing I can do is uploading the debug output from my console.

When I tried the first time a gpx upload, I've seen this messages:

Even stopping and starting JOSM didn't change this.
Maybe this helps someone to fix this.

[HeinerSchaefer]

From the OSM API wiki
​https://wiki.openstreetmap.org/wiki/API_v0.6#GPS_traces
found this:
Create: POST /api/0.6/gpx
Also available at POST /api/0.6/gpx/create (deprecated)

The DirectUpload uses this command:
POST ​​https://api.openstreetmap.org/api/0.6/gpx/create
Which is deprecated.

Fixes the command
POST ​​https://api.openstreetmap.org/api/0.6/gpx
this issue?

Is there someone who knows how to change the code and test this?

[HeinerSchaefer]

I looked into this with claude.ai and found the cause.

Cause

The request to https://api.openstreetmap.org/api/0.6/gpx/create is rejected with 417 Expectation Failed before it reaches the OSM application.
The debug log in comment:3 shows that DirectUpload sends an empty Expect header (Expect= in the request headers).
The 417 response has only 19 bytes and only a few headers (x-served-by: cache-...),
i.e. it comes from the caching layer in front of the API.

The header is set in UploadDataGui.setupConnection():

c.setHeader("Expect", "");

Reproduction without JOSM

$ curl -i -X POST -H "Expect;" https://api.openstreetmap.org/api/0.6/gpx/create
HTTP/2 417
content-type: text/plain; charset=utf-8
x-served-by: cache-dus1260020
content-length: 19

$ curl -i -X POST https://api.openstreetmap.org/api/0.6/gpx/create
HTTP/2 401
(...)

With the empty Expect header the request is rejected with 417, without it the server answers normally with 401 (missing authentication).
-H "Expect;" makes curl send the header with an empty value.

Proposed fix

The empty Expect header was probably meant to suppress 100-continue,
but the body is now sent as a complete byte array via setRequestBody(...), so it should not be needed.
Removing the line should be enough:

         c.setHeader("Content-Type", "multipart/form-data; boundary=" + BOUNDARY);
         c.setHeader("Connection", "close"); // counterpart of keep-alive
-        c.setHeader("Expect", "");
         return c;

I tested this in JOSM v19613.
