You mentioned changing SRC_URI but your steps don't include that. The SRCREV_FORMAT error suggests there were two git:// urls in SRC_URI which this bug doesn't show. I'm going to close this as unable to reproduce, if you can provide reproduction steps please reopen. For reference these issues are normally due to referencing S/WORKDIR in SRC_URI. If we need to know SRCREV to know PV to determine S/WORKDIR then that would cause a circular error.
