   > Not sure through what the problem is, maybe the Gradle upgrade?
   
   Yes, I think it was caused by Gradle version update and it's already fixed in `master`, so it just needs to be rebased

       Should we print out an error here? Can it cause NPE later?

Review comment:
       No, this should be silent ... if no region is found, the option should be `null` as it is at the moment in this case. Same regarding the NPE, this just sets a region automatically if available. Otherwise the behavior is unchanged.
   Btw, check this comment in the AWS SDK itself:
   ```
   // Note: This is a bug in the provider chain. The chain should return null when no region is found according to
    // the interface, but an exception is thrown  here instead. This class is used in too many places to change now.
   // TODO: In 2.0, be sure this bug does not carry through.
    throw new SdkClientException("Unable to load region information from any provider in the chain"

   Did you check if `Java PreCommit` fail is related or not?
