You’ll need to enable script compatibility mode for it to continue working (WaniKani > Settings > App > Compatibility Mode).

The WK team recently made a breaking change to the API, and this particular script will probably never be updated to work outside of compatibility mode, although a few people are working on making new scripts to cover the same functionality.
