Can't get google STT API working on embedded machine (AArch64)

Question

I need to get GoogleSTT installed on a machine, but the code doesn't work, it works when i'm on my computer but not on my Buildroot system.

i got this error at runtime:

    /root/node_modules/grpc/src/grpc_extension.js:57
        throw e;
        ^

    Error: File not found
        at Object.Module._extensions..node (module.js:681:18)
        at Module.load (module.js:565:32)

        at Object.Module._extensions..js (module.js:663:10)
        at Module.load (module.js:565:32)

I'm probably missing a package but all mentionned above are correctly installed, the code was tested on my computer with no error at all,

i tried cleaning cache, rebuild modules with -f

const io = require("socket.io-client");
const record = require('node-record-lpcm16');
const speech = require('@google-cloud/speech');


const client = new speech.SpeechClient();
var socket = io.connect("http://90.87.53.32:7700/");

const encoding = 'LINEAR16';
const sampleRateHertz = 16000;
const languageCode = 'fr-FR';

const request = {
    config: {
        encoding: encoding,
        sampleRateHertz: sampleRateHertz,
        languageCode: languageCode,
        enableAutomaticPunctuation: true,
    },
    interimResults: true, // If you want interim results, set this to true
};


/*class Socket {
    constructor() {
        process.on('message', (msg) => {
            this.set(msg);
        });
        process.send('loaded');
    }
}*/

const recognizeStream = client
    .streamingRecognize(request)
    .on('error', console.error)
    .on('data', data =>
        socket.emit("lol", (
            data.results[0] && data.results[0].alternatives[0]
                ? `Transcription: ${data.results[0].alternatives[0].transcript}\n`
                : `\n\nReached transcription time limit, press Ctrl+C\n`))
    );

socket.on('connect', function () {
    record
        .start({
            sampleRateHertz: sampleRateHertz,
            threshold: 0,
            verbose: false,
            recordProgram: 'arecord', // Try also "arecord" or "sox"
            silence: '10.0',
        })
        .on('error', console.error)
        .pipe(recognizeStream);

    console.log('Listening, press Ctrl+C to stop.');
    socket.emit('lol', "Message");
});

the same error occure with or w/o socket.io-client.

as my BIOS doesn't have a RTC, i have some hardcoded time update method so google may not be able to get correct date & time on my machine but i think it crashes even before executing anything

Here more infos:

Syst

uname -a

Linux buildroot 4.14.29-v8 #1 SMP PREEMPT Mon Apr 29 13:48:27 UTC 2019 aarch64 GNU/Linux the date is broken here due to lack of rtc as i said, to communicate with node servers i have to manually set correct date & time

npm ls grpc

plus: how i update machine's clock

date -s "$(wget -qSO- google.com 2>&1 | grep Date: | cut -d' ' -f5-8 | awk -v FS=' ' -v OFS=- '{print $3,$2,$1,$4}' | sed -r 's/\bJan\b/01/g; s/\bFeb\b/02/g; s/\bMar\b/03/g; s/\bApr\b/04/g; s/\bMay\b/05/g; s/\bJun\b/06/g; s/\bJul\b/07/g; s/\bAug\b/08/g; s/\bSep\b/09/g; s/\bOct\b/10/g; s/\bNov\b/11/g; s/\bDec\b/12/g' | sed 's/./ /11')"

Fixing in progress

Actions done:

Modifying l:32 of /root/node_modules/grpc/src/grpc_extension.js

binary.find(path.resolve(path.join(__dirname, '../package.json')));

The corresponding path is /root/node_modules/grpc/src/node/extension_binary/node-v57-linux-arm64-glibc/grpc_node.node which is the correct binary path

trying to ignore this will lead me to lack of functions from gRPC and enable to use it:
