Can't catch error in try/catch section, decodeAudioData-CodePudding

I have a broken .mp3 file for testing, I can't catch the error without "app crashed"

The action happens on the backend, then/catch doesn't work with decodeAudioData

const AudioContext = require('web-audio-api').AudioContext;
const context = new AudioContext();

const calcTempo = async (buffer) => {
  let audioBuffer;
  try {
    audioBuffer = await new Promise((resolve, reject) =>
      context.decodeAudioData(buffer, resolve, reject)
    );
  } catch (e) {
    console.log(e)
  }
}

/usr/src/app/node_modules/av/src/core/stream.js:489 throw new Error("Invalid utf16 sequence."); ^

CodePudding user response：

This looks like a mixed approach of Promise and async-await.

What if you tried a pure approach such as

const AudioContext = require('web-audio-api').AudioContext;
const context = new AudioContext();

const calcTempo = async (buffer) => {
  let audioBuffer;
  try {
    audioBuffer = await context.decodeAudioData(buffer);
  } catch (e) {
    console.log(e)
  }
}

CodePudding user response：

you are missing {} brackets for the callback function

try {
    audioBuffer = await new Promise((resolve, reject) =>
      { context.decodeAudioData(buffer, resolve, reject) }
    );
  }
