The validator call before uploading a data set fails...

[JND]

What steps will reproduce the problem?

1. Do some edits
2. validate & correct errors
3. upload fails with the message that there was an error in the validator plug_in

Saving the dataset restarting josm and uploading directly produces the same error.

What is the expected result?

What happens instead?

Please provide any additional information below. Attach a screenshot if
possible.

Somehow you skipped the mandatory plugin-update process when installing new version. You need to update validator.
