Issue tracker is ONLY used for reporting bugs. Please use our discord for support and/or feature requests.

Expected Behavior

• Launching an ISO would open successfully

Current Behavior

After launch, I get a black screen, and then this C/C++ error:

terminate called after throwing an instance of 'std::invalid_argument'
  what():  stoi
Aborted (core dumped)

Steps to Reproduce

1. Fresh Fedora 34 install
2. Download Slippi AppImage
3. Download the following modules to resolve Perl errors - perl-Net-DBus perl-X11-Protocol perl-Sys-Hostname
4. Launch Slippi, then click "Play"

Environment

Fedora 34

Attaching core dump in case it is useful -

Seems like launching the ISO from standalone netplay works, but not from the Slippi launcher. Going to attempt building from source with additional logging, we have a theory on Discord that the parsing of the user.json file is busted somehow

I was having the same issue just now, using Fedora 33 though, but the weird thing to me was that my other Fedora machine was running just fine. I went and checked each user.json file as you pointed out and it seems that the Slippi download process I just went through on the machine with the issue had generated a user.json file in a different format than my original user.json

I copied over that working user.json file to my machine and everything worked after that. If you don't have a good/bad user.json file to compare, here was each file's fields

Bad -
connectCode
playKey
uid

Good-
uid
displayName
playKey
conenctCode
latestVersion

Curious to see if this helps you with your issue!

That worked! Thank you so much @mitchhit234 - I will flag this in the Discord as well

There's a new issue running on Fedora 35 but it with a workaround: #323

Perhaps this should just be closed because it's old.
