Hi, I had simular problem. You just need to modify line 24 in file src/Thybag/Auth/SharePointOnlineAuth.php FROM: `$headers[] = "Content-Type: text/xml;";` TO `$headers[] = "Content-Type: text/xml; charset=utf-8;";`

Hey, I managed to fix it by installing `npm install postcss-custom-properties --save-dev`
