Description

In the app we have implemented a check for isRetryable, however users report more often logouts.

A few examples of false positives in production:

iOS
AuthenticationCredentialsTokenRenewFailedException, code: RENEW_FAILED canRetry: false message: The credentials renewal failed. CAUSE: Unable to complete the operation. CAUSE: Error Domain=NSURLErrorDomain Code=-1200. (we've noticed different code value, 1001-1005, 1009 and so on)

Android
AuthenticationCredentialsUnknownException, code: An error occurred while processing the request. canRetry: false message: An error occurred while processing the request. details: {_isRetryable: false, cause: e5.b: Something went wrong, causeStackTrace: e5.b: Something went wrong at e5.a$a$a.d(Unknown Source:55) at e5.a$a$a.b(Unknown Source:0) at com.auth0.android.request.internal.e.e(Unknown Source:176) at f5.q.s(Unknown Source:291) at f5.q.k(Unknown Source:0) at f5.n.run(Unknown Source:14) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:[1154-1156]) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:[651-652]) at java.lang.Thread.run(Thread.java:[1119-1564]) Caused by: d5.b: Something went wrong at e5.a$a$a.d(Unknown Source:52) ... 8 more Caused by: javax.net.ssl.SSLHandshakeException:

Reproduction

1. Put the phone under bad network conditions (VPN that blocks server)
2. Try to refresh the token

Expected: isRetryable is true
Actual: isRetryable is false

Additional context

During inspection I've noticed that isRetryable fields falls back to false if not found in the details.
If we can't guarantee correctness of the data from the platform, it's probably wise to make the field nullable
