Error downloading audio for Anki card (request-builder.js exception)

Description It's been working fine for years, but I just noticed it suddenly stopped working between 04/18 and 04/23 this year. While the audio plays fine in the browser popup (source: JapanesePod101), the cards are added with the audio field empty.

EDIT: turns out the audio files were indeed downloaded in the Anki media folder, the problem is simply that the Audio fields of the cards aren't populated.

The extension has permission to work 'On all sites', and checking other similar past issues in here didn't help.

This is the relevant part of the Anki setup, which I'm pretty sure is correct:

{{#*inline "audio"}}
    {{~#if (hasMedia "audio")~}}
        [sound:{{#getMedia "audio"}}{{/getMedia}}]
    {{~/if~}}
{{/inline}}

And here is the error log:
