cfdbdata not working anymore

For an unknown reason, the cfdbdata function stopped working on Google Sheets a few days back. First the arguments passed to the function now look like [object Object] instead of their values (and only the first one is set to that value, the others are null). Then, even after setting the values manually inside the function, the return value never gets back to the sheet.

I feel like Google changed something but I didn’t see any information about any announced changes.
