... as haukex said or hack your way around it: 

... warn( "Put failed: @{[$sftp->error]} \n"  ) ...

Update to response below:

The @{ ... } dereferences an array-ref. By default, the resulting string is a space separated (see $" in perlvar) concatenation of the array elements. However, $sftp->error() returns a scalar (string). Here, the square brackets come into play. They generate an anonymous array - with one single element - that finally is dereferenced and interpolated.

It's somewhat equivalent to: warn( "Put failed: " . join($", @{ [ $sftp->error() ] }) . " \n" );
