node.js – Getting error spawn ffmpeg ENOENT aws lambda

I have being trying to debug but to no avail, I’ve done everything on the internet.

I Used WSL (Ubuntu) – Error: spawn usr/bin/ffmpeg ENOENT.
I Used windows – Error: spawn path/to/ffmpeg.exe ENOENT.
I had to SAM deploy –guide and then added a lambda layer on aws console.
Moved Ffmpeg file to my project root folder also ENOENT.

Ffmpeg exists in those parts, “path/to/ffmpeg -version” prints version/other info.

I gave permissions using chmod +x, I used AI too.

3days of struggle

import { spawn } from 'child_process';
import ffmpeg from 'fluent-ffmpeg';
const isLocal = process.env.AWS_SAM_LOCAL; // Detect local SAM environment

const ffmpegPath = isLocal ? 'C:\\ProgramData\\chocolatey\\lib\\ffmpeg\\tools\\ffmpeg\\bin\\ffmpeg.exe' : '/opt/bin';

ffmpeg.setFfmpegPath(ffmpegPath);

const ffmpegArgs = [
      '-i',
      inputFilePath,
      '-vf',
      `crop=9/16*ih:ih:scale=1080:1920`,
      '-c:v',
      'libx264',
      '-c:a',
      'aac',
      '-strict',
      'experimental',
      outputFilePath,
    ];

    const ffmpegProcess = spawn(ffmpegPath, ffmpegArgs);
