Convert cwebp error in 2.1.1

TypeError: callback is not a function

My code is the following:

const converter = require('webp-converter');
const save_webp = (imagePath, cacheTime) => {
    return new Promise((resolve, reject) => {
        converter.cwebp(imagePath, imgDestination, "80", (status) => {
            //if conversion successfull status will be 'converted successfully' 
            if (status == 'converted successfully') {
                database.store(imgDestination, cacheTime);
                resolve(imgDestination);
            } else {
                reject(imageConvertError);
            }
        });
    });
}

This code is never able to complete as the app crashes with the error above before the status check. I have since reverted to v2.0.1, which I originally used and it now works, but I do not know specifically what would have caused the error

In your code, you need to define status as a callback function. TRY THIS. const converter = require('webp-converter'); const save_webp = (imagePath, cacheTime) => { return new Promise((resolve, reject) => { converter.cwebp(imagePath, imgDestination, "80", function(status) => { //if conversion successfull status will be 'converted successfully' if (status == 'converted successfully') { database.store(imgDestination, cacheTime); resolve(imgDestination); } else { reject(imageConvertError); } }); }); }

(status) => {...} is correct syntax in es6 for a function where status is the parameter, which nodejs supports, and it definitely works with v2.0.1.

function(status) => {...} is invalid js syntax However I did try:

function(status) {...}

which also failed on v2.1.1 but works on v2.0.1. I did not test any versions in between and I am fine with sticking to 2.0.x since I don't need gif conversion. Just wanted to bring up something I saw. Thanks for the quick response
