And you're thinking, what is going on? Call Sidewalk ASAP!
Never you fear, the answer is here. You have the wrong version of Java installed. You should be on Version 8.40. If you want to verify what version you have, you can look under the "Help" tab, and click on "About Sidewalk Merchant Operator."
So you need to roll back to version 8.40 then. Sadly finding an older version of Java is not so easy. Luckily for you, we have made it simple by providing you a link below. Please make sure and uninstall the current version on your machine (anything newer than 8.0_40) before installing.
Java version 8.0_40
