Unhandled Promise Rejection Warning

[insuusvenerati]

Hey I'm getting this error when trying to execute the function

gulp.task("image", () => { gulp.src("./site/static/img/*") .pipe(image({ guetzli: true, options: { guetzli: ["--quality", 85] } })) .pipe(gulp.dest("dist/img")); });

Another node module works so I know the directories are correct. The exact error is:
(node:10378) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 2): [object Object] (node:10378) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non -zero exit code. (node:10378) UnhandledPromiseRejectionWarning: Unhandled promise rejection (rejection id: 4): [object Object]

I'm having the same problem. I forced Node to crash on unhandled promise rejections (https://medium.com/@dtinth/making-unhandled-promise-rejections-crash-the-node-js-process-ffc27cfcc9dd) and I got back this:
/usr/src/app/gulpfile.js:26 process.on('unhandledRejection', (up) => { throw up }); ^ Error: spawn /usr/src/app/node_modules/pngquant-bin/vendor/pngquant ENOENT at _errnoException (util.js:1022:11) at Process.ChildProcess._handle.onexit (internal/child_process.js:190:19) at onErrorNT (internal/child_process.js:372:16) at _combinedTickCallback (internal/process/next_tick.js:138:11) at process._tickCallback (internal/process/next_tick.js:180:9)

Give it a shot so we can hopefully figure this out.

I'm also running this inside of a Docker container as well.

Any update on this? I'm currently experiencing this as well by 2/4 PNG's I'm trying to run through gulp-image.

Just had this error. Only seems to affect particular images?

This might be the issue.....

@AlexMachin1997 Your import name and the usage name is not the same.
