Yeah, the request builder is not very smart and it's allowing you to provide invalid inputs to the process. The process you are using requires just a geometry, and you're providing something else (a list of feature, that eventually might contain geometries inside). Try the gt:BufferFeatureCollection (maybe the name is not exactly that one) process instead, which is meant to work on feature collections instead.
