Error when trying to install facebook pixel

[andrewg94]

Pretty complicated problem.

This is what i did trying to install the facebook pixel, from video tutorial i was told to install Facebook channel from the apps section https://i.imgur.com/VWc26ty.png , then i watched another video, i saw that he had a section where you can simply copy the pixel id https://i.imgur.com/kBvsk3j.png , i dont have that section, instead i have a button called "Set up Facebook" https://i.imgur.com/3pDJ6hO.png , i thought maybe that section disappeared because i installed Facebook channel from the apps section, so i uninstalled Facebook channel. Now i think that section has been removed by shopify and the only way to install the pixel is to go thru all that many steps in Facebook channel. The problem is that now when i click "Set up Facebook" button this error appears https://i.imgur.com/ErttRTi.png , the same when i click on Facebook from Sales Channels https://i.imgur.com/Pr53hhL.png . Is this happening because i installed and uninstalled Facebook channel? Why is this happening? Thanks for your help
