One of the screw holes didn’t have grooves to accept a screw, so I was  able to finish the build. Because this defect is hard to see, I didn’t know it was there until I got through more than 80% of the installation. Now the bed sits there as I wait for a response to get a replacement part. I have emailed 3 days ago and no response yet.  If I wasn’t nearly complete I would return it but I’m already invested.
