Exit Status 255, Connection closed in SFTP

I'm trying to connect from Server A to Server B to transfer files from A to B. I'm using NUID A1 in Server A and NUID A2 in Server B. I have done the following the steps to setup password-less login.
1. Add the public key of A1 in A to the Authorized keys of A2 in B.
2. Add the public key of Server A to the Known hosts file of A2 in B.


The following command is used to transfer the files from A to B.
Code:
sftp -vvv -o BatchMode='yes' -b -f SourceDir/File -d Destination_Dir/File UserID Machine_Name
sftp -vvv -o BatchMode='yes' -b -f /var/tmp/fileA.txt -d /var/tmp/fileA.txt A2 ServerB

In this case the UserID is the NUID A2 in ServerB
Machine Name = Server B

Below is the output I get while attempting connection:
Code:
debug1: Connecting to Server B [Server B's IP Address] port 22
debug1: Connection established
debug1: Next Authentication method: publickey
debug1: Offering public key: /export/home/A1/.ssh/id_rsa.pub
debug1: Authentication succeeded (publickey)
debug1: Exit status 255
Connection closed

Kindly help me in resolving this issue. The NUIDs in both the servers are Non-Interactive (hence no password). However the required keys are added in the corresponding locations and verified. Any help is much appreciated and thanked !!!

You request batch mode but don't provice a batchfile. man sftp:
Quote:
-b batchfile
Batch mode reads a series of commands from an input batchfile instead of stdin.

hi RudiC,
Sorry to have not mentioned.. Yes we also pass a batch file to read inputs during the batch mode.. Still the same case. Appreciate your support.. Thanks...
