When I try to add a user, for example adding the user to the list column, it does not give auto-fill suggestions or resolve any user.
This SharePoint site was upgraded from SP2013.
Here is the console error:
Uncaught TypeError: a.set_allowOnlyEmailAddresses is not a function at SPClientPeoplePicker.GetPeoplePickerQueryParameters (clientpeoplepicker.js?rev=xQZCUuvNj423eygeQ6yOJg%3D%3DTAG0:1:6764) at SPClientPeoplePicker.AddPickerSearchQuery (clientpeoplepicker.js?rev=xQZCUuvNj423eygeQ6yOJg%3D%3DTAG0:1:5873) at SPClientAutoFill.SPClientPeoplePicker_CallbackPopulateAutoFillFromEditor [as FuncPopulateAutoFill] (clientpeoplepicker.js?rev=xQZCUuvNj423eygeQ6yOJg%3D%3DTAG0:1:37590) at autofill.js?rev=hRHNkHTVTVhEvdynOszVNg%3D%3DTAG0:1:10528 at arguments.
