<p>Hi, Alexander!</p>

<p>The <code>t_on_failure</code> is not a symbol exported by the shared library, but rather a string that maps to a function.<br>
The problem seems to be something in your script. Are you sure you are loading the <code>tm.so</code> module in your config file?</p>

<p>Best regards,<br>
Răzvan</p>
