I had the same problem, so started Codeception in debug mode with xdebug and discovered that the message had nothing to do with the actual error, because the error was in the fixtures; so loading fixtures with wrong fields leads to exception that is catched inside Codeception itself but is masked by other checks and the original exception message is lost.

Hope this helps.

@fabioaccetta thanks!
I try to trace it.

I'm not using fixtures. Actually my first day with yii2 and codeception.

[zacksleo]

same issue

[ratVien]

In my case it happens when codeception try to handle db exception in Event.php

// wildcard event names $removed = false; foreach (self::$_eventWildcards[$name][$class] as $i => $event) { if ($event[0] === $handler) { unset(self::$_eventWildcards[$name][$class][$i]); $removed = true; } }
There is empty array in $_eventWildcards not afterOpen
And there is no check for that/ I am not sure it is Yii bug or codeception...

[zacksleo]

updated: I finally found that there are some problems in my Fixtures class or dataFile

[bscheshirwork]

@ratVien you tell about this?

    public static function on($class, $name, $handler, $data = null, $append = true)
    {
        $class = ltrim($class, '\\');

        if (strpos($class, '*') !== false || strpos($name, '*') !== false) {
            if ($append || empty(self::$_eventWildcards[$name][$class])) {
                self::$_eventWildcards[$name][$class][] = [$handler, $data];
            } else {
                array_unshift(self::$_eventWildcards[$name][$class], [$handler, $data]);
            }
            return;
        }

        if ($append || empty(self::$_events[$name][$class])) {
            self::$_events[$name][$class][] = [$handler, $data];
        } else {
            array_unshift(self::$_events[$name][$class], [$handler, $data]);
        }
    }
