As @Cvanbeek said here - DKRed Incorrectly States Hole Sizes are too big - I can’t upload my gerbers to DK Red, as it throws an error that “Drill hole size must be less than 250 millimeters or less”. Unfortunately, there does not seem to be a resolution in that thread, last response is a DigiKey representative asking for his files for testing
According to my drill file (generated from Autodesk Eagle 9.6.2), my holes are .35mm and .813mm - all the board is is to correct a pin swap from an EOL 28 pin IC, so it’s essentially going to be 2 DIP 28 sockets and some vias.
The image in the preview even seems to pass the sanity check
