Am i missing a step from the Readme?

Thank for sharing.

@idkjs you can get past the error by adding the following to your migrations config:

disableForeignKeys: true, // wrap statements with 'set foreign_key_checks = 0' or equivalent.

eg.

  migrations: {
    path: path.join(__dirname, "./migrations"),
    pattern: /^[\w-]+\d+\.[tj]s$/,
    disableForeignKeys: false,
  },

However, disabling foreign keys might not be the best idea in the long run -- not sure what the exact consequences of using this flag are.

tks - foreignkeys are useless if you ask me. they will create issues once you go do a distributed model/db
plus they slow down the insertions.
