TypeError: Cannot read properties of undefined (reading 'mask')

Hi,

am facing to following issue:

    import EmojiConvertor from 'emoji-js';

    const emojiConvert = (sanitizedHTML: string, emojiSet?: string): string => {
        const emojiConvertor = new EmojiConvertor();
        const msgHtml = sanitizedHTML.replace(/\n$/,'');
        emojiConvertor.img_sets.google.sheet = '/emoji-data/sheet_' + emojiSet + '_64.png';
        emojiConvertor.use_sheet = false;

        emojiConvertor.replace_mode = 'img';
        emojiConvertor.img_set = emojiSet;
        emojiConvertor.include_title = true;

        return emojiConvertor.replace_colons(msgHtml);
    }

And when I call function

emojiConvert('hello :alien:');

I get following error:
TypeError: Cannot read properties of undefined (reading 'mask')

Screen here: https://ctrlv.cz/gpcx

I am using emoji-js version 3.6.0

Some tips?

I can't get as far as you to check, because I don't know what toolchain and VM you're using (this is typescript, so how are you compiling it and where are you running it?).

My guess would be that you're passing an invalid value to .img_set and so it's failing to find all the information it needs to initialize. What happens if you call emojiConvert('hello :alien:', 'apple'); instead?

I am sorry, my mistake. I passed emojiSet undefined.
@iamcal thanks

The errors should be less confusing!

I've just landed PR #156 on master which in future will throw an exception in this situation, explaining what is wrong.
