I am either deleting or saving model instances through sequelize, eg

User.destroy({ where: { id: id } })
.then(() => {})

var user = new User({...})
user.save()
.then(() => {})

and everytime I get the warning. I’ve tried adding return null in the then clause but that does absolutely nothing.

@opichon I’m seeing a similar problem (with Sequelize v3.30.4 - we’re not currently in a position to upgrade). Did you raise a ticket with them, or find a fix for the Bluebird warning?

Do you have the code from:

/Users/olivier/projects/kinkao/api/auth/auth.js:19:16

And

/Users/olivier/projects/kk/api/auth/oauth.js:34:21

?
