Re: 'Column name is required in ColumnIdentifier.'

I would bet the problem is that "data.contact_via_mail" is undefined. Calling "set('contact_via_mail', undefined)" is the same as not providing a second argument, which means calling "set('contact_via_mail')". This is not allowed. Ultimately depending on what you need you can do something like the following:

set('contact_via_mail', data.contact_via_mail ?? false)
set('contact_via_mail', data.contact_via_mail ?? null)
