Hello Team,

 

We have a class as below

 
{code:java}
DetailedSftpErrorStatusDataHandler implements SftpErrorStatusDataHandler, ChannelSessionAware, DetailedSftpErrorStatusDataHandler implements SftpErrorStatusDataHandler, ChannelSessionAware, AsyncCommandErrorStreamAware, CommandDirectErrorStreamAware {
{code}
and we have overridden the :

 

resolveErrorMessage and setIoErrorStream(IoOutputStream errStream) 
{code:java}
 @Override
 public void setIoErrorStream(IoOutputStream errStream) { 
     this.errStream = errStream;
 }
{code}
finally we are writing to the error stream:
{code:java}
private void writeMsgToErrorStream(String refinedUserExitMessage) {
    ByteArrayBuffer buf = new ByteArrayBuffer();
    buf.putString(refinedUserExitMessage + System.getProperty("line.separator")); 
    try { if (errStream != null) { 
        errStream.writeBuffer(buf); 
          }
    } catch (Exception e) { 
    }
 }
{code}
Once the data is written to error stream we are gettig proper message to the console:

!image-2021-08-19-12-50-01-922.png!

But there is an extra charater getting appended at the first character *<*Utils.java ....

I have no idea from where this *<* is coming from, and that changes with the first character like if it is P it would be *>, when starting with S it gets appended with Z*

Any help will be appreciated.

Thanks,

Susmit
