then have 2 api endpoints use slim framework rest api have 2 methods return data.

for employees:

    public function getallemployees(){     $this->logger->info(__class__.':'.__function__);       $employeesrepository = $this->dbentity->getrepository(employee::class);     $employees = $employeesrepository->findall();      return $employees; } 

for documents:

    public function getalldocuments(){     $this->logger->info(__class__.':'.__method__);      $documentrepository = $this->dbentity->getrepository(document::class);     $documents = $documentrepository->findall();      return $documents; } 

so problem when uncomment line

            'employees' => $this->employees->toarray() 

in document class

i runtime error recursion detected

without line works fine.

can me missing?
