Null pointer exception during submission #724

Closed alawvt closed 4 years ago

alawvt commented 4 years ago

I merged branches qdc_xsl and vtt to into vt_6_x_dev. I started the submission process for an item on vt_6_x_dev in my LDE and received a Null Pointer exception after the "Review Submission" step

Java stacktrace: java.lang.NullPointerException

I got the same error on vtechorks-dev running https://github.com/VTUL/vtechworks/pull/721/commits/e944ae816b951e7126857c700600c5b8998468a6, on branch, https://github.com/VTUL/vtechworks/tree/qdc_xsl.

Submission works fine on pprd and prod.

Oops--I just removed some diff code in bistream-formats.xml that certainly wasn't helping. I'll test that.
