Generic Error message from MSIX upload

Type of issue

Missing information

Feedback

To actually see any error messages, you have to manually refresh the page. The error system is very generic, with no real actionable information.

Here is an example from submitting a .msix that passes the latest Windows App Cert tests:

• You must upload at least one package. If you are using market groups, then each market group must have at least one package.
• You must provide a package that supports each selected device family (or uncheck the box for unsupported device families). Note that targeting the Xbox device family requires a neutral or x64 package.
• The package *.msix is taking a long time to process. If this isn’t completed soon, try refreshing the page, or remove the package and then upload it again. If you continue to see this issue, contact support.
• You must fix all package validation errors before submitting.

Clearly there is a deeper root cause that is not being tested for or exposed here.

Alright, so I figured out that it doesn't do well with special characters. I as trying to make it so I could drop a shortcut to a special folder on my computer anywhere I wanted, and at first I thought it just couldn't do shortcuts (maybe something to do with a path in a path or something. but I got it to work. And here's the result:

When the folder was named "Impala", it worked great. But if I changed the folder name to "❇️Impala❇️", it broke it. Furthermore, I think it's an issue not only with the direct folder name, but with any special characters in the delivery path; because when I had it named "Impala" and tried to create it with the template folder on my "C" drive and and the destination on my "D" drive, it wouldn't work, but then it did when I was just going from "C" to "C" (template folder to a folder on my desktop. The thing with that is, I name my files and folders all kinds of wacky names. I use emojis as kind of a coding system for my files. So I name active projects like "⚡Project⚡" and a dead project like "☠️Project☠️" and finished projects like "🏆Project🏆"

Considering that it worked and worked and worked, and as soon as I added a "❇️" it broke, I'm assuming that even when it WAS just named "Impala" on my earlier attempts, it's because it was traveling from "%USERPROFILE%\AppData\Local\Microsoft\PowerToys\NewPlus\Templates" TO "D:\📄Projects📄\Test"

But then suddenly worked traveling to "%USERPROFILE%\Desktop\New folder\Impala" Until of course I changed it to "%USERPROFILE%\Desktop\New folder\Impala❇️" at which point it immediately broke again.
