Hello,

I have the same Problem.
In the new version is the ISendMailOptions required but there is no params for: To, Cc, Bcc, From.
See here:

import { SendMailOptions } from 'nodemailer';
export interface ISendMailOptions extends SendMailOptions {
    template?: string;
    context?: {
        [name: string]: any;
    };
}

So be careful to Update to the Nestjs version 6.x because the Mailer isn't working at the moment.

Any solutions?

@MegaphoneCA super strange I just removed the class for sendMailOptions:

// from
import { SentMessageInfo } from 'nodemailer';
/** Interfaces **/
import { MailerOptions } from './interfaces/mailer-options.interface';
import { ISendMailOptions } from './interfaces/send-mail-options.interface';
export declare class MailerService {
    private readonly mailerOptions;
    private transporter;
    constructor(mailerOptions: MailerOptions);
    sendMail(sendMailOptions: ISendMailOptions): Promise<SentMessageInfo>;
}

// to
import { SentMessageInfo } from 'nodemailer';
/** Interfaces **/
import { MailerOptions } from './interfaces/mailer-options.interface';
import { ISendMailOptions } from './interfaces/send-mail-options.interface';
export declare class MailerService {
    private readonly mailerOptions;
    private transporter;
    constructor(mailerOptions: MailerOptions);
    sendMail(sendMailOptions): Promise<SentMessageInfo>;
}

After reloading Nest App it should be working than.
After this you can add the Class to the Options and reload again and it still working.

Maybe it's a caching problem?
I uninstalled the Package and install it again and its still working.

How?

I'm confused, with your instructions... Can you clarify exactly what steps I need to take?

[mfeldmeier]

Go to the mailer.service.d.ts :

import { SentMessageInfo } from 'nodemailer';
/** Interfaces **/
import { MailerOptions } from './interfaces/mailer-options.interface';
import { ISendMailOptions } from './interfaces/send-mail-options.interface';
export declare class MailerService {
    private readonly mailerOptions;
    private transporter;
    constructor(mailerOptions: MailerOptions);
    sendMail(sendMailOptions: ISendMailOptions): Promise<SentMessageInfo>;
}

In the sendMail function is the parameter sendMailOptions. This is from Type ISendMailOptions
Remove this at first, save the file and reload your application.

Now you shouldn't get any error.

Go again to this file and add ISendMailOptions to the sendMailOptions.

sendMailOptions:ISendMailOptions

Save again and reload your application.
This works for me and all is working now.

Is that easier to understand?

That wasn't the part I found confusing. I am hoping for a fix that will be integrated into the project and not something I have to do myself.

Will the code you shared be integrated into the NPM version? If I change the code in my node_modules folder than it is only local and won't carry over to my production environment.

[mfeldmeier]

It's weird.
Because I change it and put it back again.
It looks like a bug but it would work.
So I don't know if or how you can fix something like that in an npm module.

Maybe this is just a temporary fix.

[ahmadarif]

I've the same problem, and downgrade to v1.0.4 :D

[justinlazaro-ubidy]

i have a same issue here. hoping for documentation about the implementation.

export interface ISendMailOptions extends SendMailOptions {
    template?: string;
    context?: {
        [name: string]: any;
    };
}
