Investigate automaticRadius deserialization issue

[aseure]

A user reported the following issue by email to us:

Thank you for reading this. I have a quick question and I am wondering if you could help :) I am using Algolia geosearch in my Golang backend, version 3.0.0. I am trying to call like this:

index = client.InitIndex("PartiersLocation")
res, err := index.Search("",
                           opt.AroundLatLng(
fmt.Sprintf("%f, %f", partier.Location.Lat, partier.Location.Lng))

And in the documentation here it seems like this should just work. but it does not work. I am getting this error message about automatic radius:

cannot deserialize response's body: json: cannot unmarshal string into Go struct field QueryRes.automaticRadius of type float64

Everything works correctly when I specify a radius like so:

res, err := index.Search("",
                           opt.AroundLatLng(fmt.Sprintf("%f, %f", partier.Location.Lat, partier.Location.Lng)),
                           opt.AroundRadius(20000))

but I believe I shouldn't have to do that according to the documentation.

What is wrong here? Am I doing something wrong? Or calling something incorrectly? Would love your thoughts.
