There is a data resource in the marketplace that uses this service and it works well. I tried to clone it and modify it with the service I need: https://maps.googleapis.com/maps/api/place/autocomplete/json but I always get the same error. I have tried other Places services but I always get the same error.
This doesn’t really make sense.
I tried with both “?” And without. I have done dozens and dozens of possible tests and joints and from what I can see the “?” Is added in any case, even if not specified. I would rule it out as the cause of the error, sadly
The absurd thing is that there are many other messages on this forum related to the same error or very very similar errors and cases but none are reporting a solution.
