Invalid UUID on dependency build

We have started getting an error on all of our dependency builds. Running RTC 4.0.1 with dependency builds on z/OS. It happens almost immediately, apparently in the build preprocessing.  The error is

Accepting changes into workspace "Build for z/OS Test Stream (zOS Code Only) Workspace"...
com.ibm.team.repository.common.TeamRepositoryException: java.lang.IllegalArgumentException: invalid UUID []

I found another forum question on this that said to add a build property "team.enterprise.build.dependency.forceFullAnalysis" and set it to true, but that didn't seem to make a difference.

I've tried changing the JAZZ_USER to be the owner of the stream and have removed it to run as ADMIN.. no apparent difference.

My log looks like:

Should build occur?
Pre-build participant "com.ibm.team.enterprise.build.common.IFileAgentJazzScmConfigurationElement" would like to build.
The JAZZ_USER build property is not specified.  The build pre-processing code will be running under the ADMIN user ID.  If you wish to run the build pre-processing code under a user ID other than ADMIN, define the JAZZ_USER build property either in your build engine or your build definition.
