Custom config causing Uncaught SyntaxError: Unexpected token ':'

[stillhartkonzept]

Describe the bug
Example ckeditor.js does not work for me. I tried copying the example code in the first ckeditor.js in the documentation and I got console error "Uncaught SyntaxError: Unexpected token ':'" and strapi failed to compile. I tried changing the name of the file to ckeditor.txt and strapi ran, but my new config wasn't visible. I required the code in #127 (comment) AND a file called ckeditor.txt for my new config to work.
I'm running strapi 4.25.9 using node 18.

To Reproduce
Steps to reproduce the behavior:

1. Install a new version of strapi
2. Install the ckeditor plugin
3. copy the example text in the documentation at https://github.com/nshenderov/strapi-plugin-ckeditor into ckeditor.js
4. run develop

Expected behavior
The config that's documented by the example becomes available as "My Custom Preset"
What actually happened: I got "Uncaught SyntaxError: Unexpected token ':'" and strapi failed to run.

Hello, I had the same problem recently. To fix it, I changed the format of the CKEConfig() function.
I pretty much put presets into an object (it being the "configuration" object) and returned it.

const CKEConfig = () => {
    return {
        presets: {
        myCustomPreset: {
            field: {...},
            editorConfig:{
                plugins: [...],
                toolbar: [...],
                heading: {...},
                image: {...},
                table: {...}
            }
        }
    }
}}```

There is a typo in the example, I forgot to include the parentheses
