DistanceConfigFetcher -> Error:Can't construct URL from:

[iGhibly37]

I was using this library to create an app for proximity scanning beacon, but I'm having some issues with this particular method in an Interfacem DistanceConfigFetcher, in which if I use BeaconManager.setDistanceModelUpdateUrl("anyKindofUrl"), and i pass any url or null to set the default settings, it doesn't work and generates an error that is present in the title of this issue. I'm using the 2.21.1 version of this library.
I tried every manner to avoid this issue but nothing worked. Pls help me.
I add to the thread that at this moment I need to mantain disabled all the firebase services. Thank you for your answers.
