Evaluation failed error while trying to upload audio file (audio/ogg; codecs=opus)

[NovelProfessor]

Is there an existing issue for this?

• I have searched the existing issues.

Is this a problem caused by your code, or is it specifically because of the library?

• I have double-checked my code carefully.

Describe the bug.

I'm getting the error Evaluation failed when trying to upload audio file in "audio/ogg; codecs=opus" format. I am using NodeJS FFMPEG library to convert the MP3 file to OGG and sending the OGG file. I know that MP3 uses ACC and since AAC is a licensed format, It is not supported by Chromium, that's why I am converting to OGG but even OGG format is not working with your library.

Error returned:

Expected Behavior

It should send the audio file successfully as an audio message

Steps to Reproduce the Bug or Issue

I have pasted my NodeJS code below. The "sourceMediaFilename" points to the source MP3 and "targetMediaFilename" points to the converted OGG. I have attached both files here for reference. Also you can browse my full server code in my Github repository: https://github.com/NovelProfessor/whatsapp-server
You can check from line 386 in my "server.js" file.

        ffmpeg()
            .input(`${sourceMediaFilename}`)
            .outputOptions([
            '-c:a libopus',
            '-b:a 128k'
            ])
            .output(`${targetMediaFilename}`)
            .on("end", async () => {
                console.log("Conversion finished");
                const mediaObject = MessageMedia.fromFilePath (targetMediaFilename);

                await client.sendMessage(req.body.receiver, mediaObject);
                res.status(200).json({statusCode: '000', statusDesc: 'media uploaded successfully'});
            })
            .on("error", (err) => {
                console.error("Error:", err);
                res.status(500).json({statusCode: '003', statusDesc: err.message});
            })
            .run();

Additional Context

Please resolve this issue, I am the developer of the famous Novel Messenger client for BlackBerry and its based on your WWebJS library, the users are loving my app, only thing missing is the ability to send audio messages because of this bug in your libary.

Could you please try changing line 399 from

await client.sendMessage(req.body.receiver, mediaObject);

to

await client.sendMessage(req.body.receiver, mediaObject, {sendAudioAsVoice: true});

and let me know

Thanks JestiferHarold for your quick reply, I tried it but it didn't work, I'm getting the same error.

I tested and it works like a charm

[NovelProfessor]

Ok BenyFilho, you are right. I created the below standalone test script (index.js) just to test uploading my OGG file directly when the Client is ready, and it works, it is sending the audio file successfully. So I think there is some error in my server side code (server.js), I will have to debug.

const { Client, MessageMedia, LocalAuth } = require('whatsapp-web.js');
const qrcode = require('qrcode-terminal');

const client = new Client({
    authStrategy: new LocalAuth()
});

client.once('ready', async () => {
    console.log('Client is ready!');

    const targetMediaFilename = '/Users/novelprofessor/Documents/Audio_files/6897726acb3ba5d21ba68274.ogg';
    const receiver = '966549014671@c.us';

    const mediaObject = MessageMedia.fromFilePath (targetMediaFilename);
    await client.sendMessage(receiver, mediaObject, {sendAudioAsVoice: true});
    console.log('Audio sent');

});

client.on('qr', (qr) => {
    console.log('QR RECEIVED', qr);
    qrcode.generate(qr, { small: true });
});


client.initialize();

Thank you guys, I'm closing this ticket since there is no issue in your library "whatsapp-web.js", the functionality is working as expected, the issue is from my code.

@NovelProfessor what was the issue with your code? I can't find the root cause in mine. In my case, ogg files succeed, but mp4 fail. However, sending the same m4a file directly in the chrome browser by manually dragging it works...
