onBeforeUploadItem not working in versions >1.4

[elementalTIMING]

For a long time I was working with version 1.4. Now I've updated to v3.0.0. Unfortunately, onWhenAddingFileFailed is not called anymore. I also tried other versions > 1.4, but with the same result. I tried to upload files of a wrong file format and file with a too big file size and expected that onWhenAddingFileFailed is called, but no...

I'm wondering if I'm doing anything wrong or if there are any breaking changes (the documentation is a bit creepy)?

	const url = {
		url: myurl,
		additionalParameter: {
			directory: mydirectory,
			filename: myimage,
			allowOverride: false,
		},
		allowedFileType: ['image'],
		maxFileSize: 1 * 1024 * 1024,
	};

	this.uploader = new FileUploader(url);

	this.uploader.onWhenAddingFileFailed = (item, filter, options) => {
		console.log(item, filter, options);
	};

Does anybody has an idea or solution for my please?

I have the same issue, the upgrade of ng2-file-upload from v1.4 to v2 and v3 caused a bunch of on* methods to stop working including onWhenAddingFileFailed.

The issue seems to be this line https://github.com/valor-software/ng2-file-upload/blob/21e04deafe36f96e617014056561c246bcc51759/libs/ng2-file-upload/file-upload/file-uploader.class.ts#L120C34-L120C34

If this._failFilterIndex is 0 then the statement isn't executed; 0 is a valid value for the array here. It should be changed to

        if (!!this._failFilterIndex) {

The issue seems to be fixed in v4+
