Doh, yes, Shannon’s right! I didn’t look closely enough before I deleted it, but there probably is a missing UUID!
Looking back, I replaced all the UUID’s with <<REMOVED>> for you because you probably don’t want those to be public. I can’t see or revert it to the original, but looking at it, your last measurement has just
"":-9999} so it looks like I didn’t replace the UUID there, there wasn’t one.
