launchd not working properly

Hi
I installed automysqlbackup on my mac server 10.10.5 and it works when i triger the script in the terminal and i get a dump of all tables and content.
But when i triger the same script with the launchdaemon script (Library/LaunchDaemons/), i only get a Dump of the Table headers. its weird. Is there a problem with launchd or with the user rights? Or any othe suggestions?

Thanks for Help!

Here the launchd.plist script i use:

<dict>
<key>Label</key>
<string>com.td.automysqlbackup</string>
<key>ProgramArguments</key>
<array>
<string>/usr/local/mysql/bin/automysqlbackup</string>

<key>QueueDirectories</key>

<key>StartCalendarInterval</key>
