One of our users asked to filter images by file type. This is supported in Google by using the filetype:x operator, where the x is the image extension (png, jpg, etc.)
In the past, we've implemented a validator that disallowed using certain filetype: values in https://github.com/serpapi/SerpApi/pull/3278, and suggested using tbs with the ift=x value. This seems to no longer work, and the filetype: is the correct approach.
EDIT. It looks like the tbs=ift:x is supported as opposed to the tbs=ift=x as suggested in the error message. However, I believe we should still allow filetype searches, or at least update the error message to ift:x instead of ift=x.
