422 Unprocessable Entity When Sending Attachments via Novu API
@Pawan Jain @Support Hi, is there any progress or solution for my attachment problem? I have already tried even with the base64 string of my document, calculated separately, and it still throws me an error. I was checking that the errors always fail in step 3, of the connection to the bridge, but already that is going beyond what I understand of how Novu works.

Just now I was checking and the error it gives is from the bridge point, I have it as local studio, could this have something to do with it? Do I need to do something additional? Another idea, is that the payload has a maximum length and my file is exceeding it?

Yes with this example: 
import { Novu } from '@novu/node';
 
const novu = new Novu('<NOVU_SECRET_KEY>');
 
novu.trigger('<WORKFLOW_TRIGGER_IDENTIFIER>', {
  to: {
    subscriberId: '<SUBSCRIBER_ID>',
  },
  payload: {
    attachments: [
      {
        // base64 format
        file: 'iVBORw0KGgoAAAANSUhEUgAAAAoAAAAKCAYAAACNMs+9AAAAFUlEQVR42mNkYPhfz0AEYBxVSF+FAP5FDvcfRYWgAAAAAElFTkSuQmCC',
        name: 'blue.png',
        mime: 'image/png',
      }
    ],
  },
});
import { Novu } from '@novu/node';
 
const novu = new Novu('<NOVU_SECRET_KEY>');
 
novu.trigger('<WORKFLOW_TRIGGER_IDENTIFIER>', {
  to: {

I remove my typing restrictions and tried base64, but had the same 500 error.

I've tried but file type does not allow me to use a string value: 
export interface IAttachmentOptions {
    mime: string;
    file: Buffer;
    name?: string;
    channels?: ChannelTypeEnum[];
    cid?: string;
    disposition?: string;
}
export interface IAttachmentOptions {
    mime: string;
    file: Buffer;
    name?: string;
    channels?: ChannelTypeEnum[];
    cid?: string;
    disposition?: string;
}

I'm using pdfkit, and this is my code: 
generateCertificate(name: string, level: string): Promise<Buffer> {
    const date = this.getCurrentDate();
    this.addBackgroundImage();
    this.addCertificateText(name, date, level);
    this.doc.end();

    return this.getPdfBuffer();
  }

getPdfBuffer(): Promise<Buffer> {
    return new Promise<Buffer>((resolve, reject) => {
      this.doc.on('end', () => {
        const pdfBuffer = Buffer.concat(this.buffers);
        resolve(pdfBuffer);
      });
      this.doc.on('error', reject);
    });
generateCertificate(name: string, level: string): Promise<Buffer> {
    const date = this.getCurrentDate();
    this.addBackgroundImage();
    this.addCertificateText(name, date, level);
    this.doc.end();

    return this.getPdfBuffer();
  }

getPdfBuffer(): Promise<Buffer> {
    return new Promise<Buffer>((resolve, reject) => {
      this.doc.on('end', () => {
        const pdfBuffer = Buffer.concat(this.buffers);
        resolve(pdfBuffer);
      });
      this.doc.on('error', reject);
    });

This is my code:

Thanks, fyi, I tried the docs example (with base64 image example) and it worked... so I don't know if its a file type or a file size issue.
