Amazon iOS Mobile SDK v2 Create empty folder -

i have question related amazon ios mobile sdk v2. have task create empty folder inside provided bucket. create empty folder using method:

- (void)createdirectory:(awss3object *)directory inbucket:(awss3bucket *)bucket success:(void (^)())success failure:(void (^)(nserror *error))failure {     nsstring *configurationkey = [nsstring string];      if (self.configurationtype == amazonserviceconfigurationtypedefault)     {         configurationkey = s3configurationkey;     }      else if (self.configurationtype == amazonserviceconfigurationtypehub)     {         configurationkey = s3hubconfigurationkey;     }      else if (self.configurationtype == amazonserviceconfigurationtypetemporary)     {         configurationkey = s3temporaryconfigurationkey;     }      awss3 *s3 = [awss3 s3forkey:configurationkey];      awss3putobjectrequest *putobjectrequest = [awss3putobjectrequest new];      putobjectrequest.key = directory.key;     putobjectrequest.bucket = bucket.name;     putobjectrequest.body = [nsstring string];      [[s3 putobject:putobjectrequest] continuewithblock:^id(awstask *task)     {         if (task.error)         {             nserror *error = task.error;              failure(error);         }          else         {             success();         }          return nil;     }]; } 

with method getting error: the request signature calculated not match signature provided.

my access , secure keys correct.

from previous experience, used error because of incorrect parameters.

my key: aws ios sdk v2 test/test/

my bucket: abc-test

previously, when using aws ios mobile sdk v1, practically same code has been working charm.

does know, problem?

i able reproduce problem, cause of problem trailing slash of key value has been stripped nsurl.path ,lead incorrect request signature error. fix aws mobile sdk in future release. bringing our attention.
