Hi, can you provide the code that throws this error?

[hamidqp]

Its Update! when someone tap on the poll that created by robot, telegram will send that update and zanzara shows that cannot process that update included Poll.

Released 0.5.2 with the fix. We have also added the polls listener:

<?php

$bot = new Zanzara("TOKEN", $config);

$bot->onPoll(function (Context $ctx) {
    $poll = $ctx->getPoll();
});
