What happened?

When linking the latest version of SM to Civitai by API key, it consistently returns 'An error occurred deserializing the response'. Key works fine via other avenues. I was able to link a different computer a few days ago, with no error, so it seems like something in the latest update broke

Steps to reproduce

Generate an API key on Civitai
Open Stability Matrix (2.15.2)
Go to Settings/Accounts
Select Connect on the Civitai line
Paste/type your API key in
Select Connect
Receive error

Relevant logs



Version


2.15.2

    Yeah this is due to an API change from Civitai in the request format and wrapping their response in an array. Should have fix soon.

    Literally tried setting this up for the first time yesterday, and couldn't figure out how I was so stupid that I couldn't get an API cut and paste right. Patiently awaiting a fix. Please and thank you.

    I walk away from generating for OOONE day and civitai goes kaboom. Man... I was enjoying the built in browser to easily download, eager for the patch
