Description

TypeError: query[queryDataKey].split is not a function
  File "server.js", line 12723, col 52, in <anonymous>

This stacktrace was a bit difficult to decode, but I was able to pin it down to this line:

https://github.com/WordPress/openverse-frontend/blob/94fb35469ad28cc3cfd3d1b9ef877b695925a736/src/utils/search-query-transform.ts#L202

It appears that, while qquery[queryDataKey] may not be falsy from the check above, it might not be the correct type which is expected of an object that has the .split function available.

Reproduction

I was unable to reproduce this myself.
