¿Why is Unity IAP Obfuscator not creating the googleplayTangle files?

Recently i have been trying to implement the receipt validation in Unity IAP following the manual but I´m having problems when i try to obfuscate my encryption keys.

I copy my google play public key in the obfuscation window and click the button but it does not create the files, and in the console i get this log

And when in my code i use this line:

var validator = new CrossPlatformValidator(GooglePlayTangle.Data(),
			AppleTangle.Data(), Application.bundleIdentifier);

I get a compilation error stating that the files GooglePlayTangle and AppleTangle does not exist in the current context. Even after I did the Public Key Obfuscation process.

I am currently using Unit 5.3.5

I also have this problem … tell me how to solve it?
