WMS getfeatureinfo popup problem

[feryomon]

i got a problem in my first image below, WMS getfeatureinfo popup is showing "Single value expected for request parameter version but instead found: [1.3.0, 1.1.1]".

• Activated getfeatureinfo
• QGIS 3.10 LTS and QGIS2WEB ver 3.16 (latest)
• PostGIS database
• Geoserver 2.8
• CORS Enable on tomcat
  

But , when i try to use L.TileLayer.BetterWMS.js https://gist.github.com/rclark/6908938 , it does work well (see. image bellow)
