options.usernameQueryFields needs to be set to default empty array

[thisancog]

When the option 'usernameQueryFields' is specified by the user, the following error occurs:

…/passport-local-mongoose/index.js:36
options.usernameQueryFields.push(options.usernameField);
TypeError: options.usernameQueryFields.push is not a function

This should be solved by initiating options.usernameQueryFields in index.js as such:

options.usernameQueryFields = [];

As option usernameQueryFields should be provided as an array or in case not provided is prepopulated as an array I don't see the issue here. Perhaps a type check for isArray after line 35 would make sense to prevent problems

In

passport-local-mongoose/index.d.ts

Line 63 in 60691ec

usernameQueryFields: Array<string>;

that option is defined as an array of strings, so I don't even see an issue when using typescript.

i am using the email as the username in my code, I also added the plugin into the schema as defined in the doc.
I am trying to authenticate, but its not working.
Its doing the redirecting to the failed route define in the redirect.

UserSchema.plugin(passportLocalMongoose, {
usernameField: "email",
usernameQueryFields: ["email", "password"],
usernameUnique: true,

The login route is as below
router.post("/login", passport.authenticate("local", { failureRedirect: "/auth/login/failed" }), (req, res) => {
res.send("Wawou");
});
