"Querying remote for config....Failed" with exception thrown #423

Closed derrickstolee closed 3 years ago

derrickstolee commented 4 years ago

Here is a stack trace during a scalar clone operation:

Authenticating...Succeeded
Querying remote for config...Failed
Cannot clone @ E:\o3: System.NullReferenceException: Object reference not set to an instance of an object.
   at Scalar.Common.Http.CacheServerResolver.TryResolveUrlFromRemote(String cacheServerName, ServerScalarConfig serverScalarConfig, CacheServerInfo& cacheServer, String& error) in E:\A\_work\14\s\Scalar.Common\Http\CacheServerResolver.cs:line 55
   at Scalar.CommandLine.ScalarVerb.ResolveCacheServer(ITracer tracer, CacheServerInfo cacheServer, CacheServerResolver cacheServerResolver, ServerScalarConfig serverScalarConfig) in E:\A\_work\14\s\Scalar\CommandLine\ScalarVerb.cs:line 383
   at Scalar.CommandLine.CloneVerb.DoClone(String fullEnlistmentRootPathParameter, String normalizedEnlistmentRootPath) in E:\A\_work\14\s\Scalar\CommandLine\CloneVerb.cs:line 237
   at Scalar.CommandLine.CloneVerb.Execute() in E:\A\_work\14\s\Scalar\CommandLine\CloneVerb.cs:line 133

The NullReferenceException is thrown probably due to a null serverScalarConfig here, which is provided from CloneVerb.DoClone() by way of ScalarVerb.QueryScalarConfig(). Somehow we are returning null there, and we should catch it during DoClone() instead of where we throw.
