lftp works, but exits with a non-success status

To whomever it concerns,

     I have a script that uploads some files for me, and then I check
lftp's exit status for success.  It normally works fine, but for some
reason it's returning an exit code of 1, instead of 0 in this script.  I've
attached a log of me running lftp in debug mode.

Here is my .lftp/rc

> ​set net:timeout 5
> set net:max-retries 3
> set net:reconnect-interval-base 5
> set xfer:clobber on


Here is the command I'm using​

>    lftp -du $FTP_USER,$FTP_PASSWORD sftp://$FTP_HOST 2>&1 \
>       <<eot |tee -a $OUTPUT_LOG
>       cd "$target_dir"
>       mput "$file"
>       quit
> eot



Why am I getting exit code 1, when the file is uploaded correctly?
