Autocomplete without location and radius and with strictbounds gives INVALID_REQUEST

[1140251]

I can't call the autocomplete function without location and radius.
I copied the request made by the autocomplete function and performed it in postman to check what was wrong.
If I make any request with the flag strictbounds will look for the location and radius, but I don't want to specify one.

An example
https://maps.googleapis.com/maps/api/place/autocomplete/json?input=googleplex&strictbounds=false&key=my_key&sessiontoken=my_token

if removed the strictbounds it works
https://maps.googleapis.com/maps/api/place/autocomplete/json?input=googleplex&key=my_key&sessiontoken=my_token

Can you remove the flag strictbounds if no location and radius is specified?
