getting NullPointerException error while uploading

[rahilarious]

Made many changes (guilty), hours of work, around 1105 objects to upload.

While trying to upload, first validator gives me error

Highway duplicated nodes(1)
2 nodes: 2211718725, 2211718711

When I try to upload changes anyway, bug window shows up with stack trace (attaching with ticket)
When I press "Ignore this error" and try to upload, I get "bad request" error.

The OSM server 'https://api.openstreetmap.org/api/0.6/' reported a bad request.
Error message(untranslated): Node 2211718711 does not include all mandatory fields at line 331, column 61

Thanks for the log, but you should have used the report bug button in the popup. There are some things it would have added for context, like any plugins you have installed. I'll go ahead and use the [[BadReport]] macro so you know how to get the information to attach.

I suspect that a plugin fiddled with the data, and a node (somehow) has no coordinates. Can you save the data to disk and upload a copy here?

I'll go ahead and copy the error from the log into this comment.

Thanks for your report, however your ticket is incomplete and therefore not helpful in its current form.

Please add all needed information according to this list:

• The required parts of the Status Report from your JOSM.
  • Please, use Report Bug from Help menu and copy & paste.
• Describe what behaviour you expected.
• Describe what did happen instead.
• Describe if and how the issue is reproducible.
• Add any relevant information like error messages or screenshots.

To ensure that all technical relevant information is contained, create new tickets by clicking in JOSMs Main Menu on Help → Report Bug.

Remember: This is a generic notice so we don't need to write the same stuff again and again. It may only apply in parts to the specific case!

Thanks for rapid response. I already attached stacktrace which I thought was enough to debug. https://josm.openstreetmap.de/attachment/ticket/23132/stacktrace.txt

However I solved it. Turned out .osm, .jos, .joz (zip compressed .jos) are just a xml files which I can edit. As I already had faulty node IDs I searched, found & deleted lines containing ids in .osm file.

<node id='2211718711' visible='false' version='2' />
<node id='2211718725' visible='false' version='2' />

Tried to upload again. Voila it worked. I still don't know why those deleted nodes were "visible" on my viewport.
