let r = await User.createUser(req.body.username, req.body.password. req.body.role) //throws error on this line
console.log(r)

你在这一行有一个错别字：

let r = await User.createUser(req.body.username, req.body.password. req.body.role)

let r = await User.createUser(req.body.username, req.body.password, req.body.role)
