Accounts.onEmailVerificationLink throws console warning when being used

[dcantatore]

When you use Accounts.onEmailVerificationLink() on the client side as instructed, in the console it says:

Accounts.onEmailVerificationLink was called more than once. Only one callback added will be executed.

The meteor doc around it is:
https://docs.meteor.com/api/passwords.html#Accounts-onEmailVerificationLink

It says "This function should be called in top-level code". Which it is, so I'm not sure where else I would put it to avoid this bug

I have seen this mentioned as a feature request but this is a bug

Hi, could you provide a reproduction? 😉 Read more here

Hi @filipenevola ,

It's really simple, create a new meteor project and add:

Accounts.onEmailVerificationLink((token, done) => {
    Accounts.verifyEmail(token, (err) => {
        if (err) {
            console.log('Error: ', err);
        } else {
            done();
            console.log('Success');

        }
    });
});

It can be put in any top level code 'This function should be called in top-level code, not inside Meteor.startup().' as stated here:
https://docs.meteor.com/api/passwords.html#Accounts-onEmailVerificationLink

Could be related to this reported problem/bug : [1.8.3] onLogin handler fired twice #10853

The above onLogin handler fired twice bug was reported to be related to this code change & commit: Simplify _startupCallback by passing callback rather than ID. (ec0ed4d)

Which was introduced in this PR #10543 which was resolving this bug/issue: #10157

I also have this issue. I understand there may not be an easy way to reproduce this, but thought I'd chime in for the record.
