Wrong stream is selected when starting a build using the REST API on a specific revision of stream-enabled Perforce VCS root

Symptoms

When starting a build using the /app/rest/buildQueue endpoint on a specific revision of stream-enabled Perforce VCS root, the build starts on the primary stream instead of the one specified in the branchName or vcsBranchName.

Cause

Stream is not specified in the revision version as expected by stream-enabled Perforce VCS roots.

Resolution

Stream-enabled Perforce VCS Roots expect the revision version in the format <stream>|<revision>.

E.g., <revision version="<stream>|<revision>"...
