Publish over Dropbox returns "ERROR: Exception when publishing, exception message [null]"

XMLWordPrintable

      When the pipeline gets to publishing step it returns this:

      ERROR: Exception when publishing, exception message [null]

      The stack trace is as follows:

      java.lang.Exception: UNSTABLE
	at org.jenkinsci.plugins.publishoverdropbox.impl.step.DropboxPublishStepExecution$1.run(DropboxPublishStepExecution.java:90)

	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)
	at java.lang.Thread.run(Thread.java:748)

      And this is the stacktrace from Jenkins system log:

      UPDATE: Just confirmed that when the pipeline gets to Upload step, the request doesn't even reach the proxy server. Now I'm not sure if the error is caused by that, or the fact that the request doesn't reach the server is caused by the __

      NullPointerException
