**Steps to replicate the issue** (include links if applicable):
* Visit Special:ContentTranslation in Serbian Wikipedia
* Change source wiki/language to Croatian (hr)
* Choose the article `Kapuljača` to translate
**What happens?**:
Content translation opens and loads, with the error:
{F41503436}
**What should have happened instead?**:
It shouldn't throw any error, but to allow me to translate.
**Software version** (skip for WMF-hosted wikis like Wikipedia):
Serbian Wikipedia, which is having 1.42.0-wmf.4 (de18cff) at this moment, ContentTranslation - 17376f4
**Other information** (browser name/version, screenshots, etc.):
* Microsoft Edge 119.0.2151.58 64-bit
* Windows 11
I've had no luck translating that article for a couple of months now, I'm getting superstitious.
It was just loading forever earlier when I was trying, now it's throwing an error at least.
The browser console is showing me only: `mw.cx.init.Translation.js:234 [CX] Translation initialization failed.`
(you can actually see it in the screenshot)
