I seem to miss the meaning of this exception and error message. Hoping someone who uses symfony more than i do can help here.

log.ERROR: exception 'Symfony\Component\Debug\Exception\FatalErrorException' with message 'Using $this when not in object context' in /var/www/vendor/jeremeamia/SuperClosure/src/Jeremeamia/SuperClosure/SerializableClosure.php(99) : eval()'d code:3 Stack trace: #0 [internal function]: Illuminate\Exception\Handler->handleShutdown() #1 {main} [] []

code in quesiton is this line.

    eval("\$this->closure = {$__code__};");

from the following function

public function unserialize($serialized) { // Unserialize the data we need to reconstruct the SuperClosure $this->state = unserialize($serialized); list($code, $context) = $this->state;

    // Simulate the original context the Closure was created in
    extract($__context__);

    // Evaluate the code to recreate the Closure
    eval("\$this->closure = {$__code__};");
}
