Are you trying to play it using a real-life console? I don’t have one, so I only tried it using the SDK emulator

The pdxinfo file needs additional fields filled out in it for sideloading via a user's play.date account. More info here: https://sdk.play.date/#pdxinfo. The docs don't indicate which fields are required, but I believe it might just be bundleID. I would recommend included that as well as name, author, and version at a minimum.
You should be able to open the .pdx file (it's really just a zip file I believe), edit the pdxinfo file to add the necessary fields, and package it back up into a .pdx. Then adding the game via the Sideload page in your account would work.
FWIW, I believe you can directly add the game via USB without a valid pdxinfo file if you'd rather go that way.
you can run it on divece if you edit the pdxinfo to be something like this.
