The expression return $this->transactionManager could return the type null which is incompatible with the type-hinted return ArangoClient\Transactions\TransactionManager. Consider adding an additional type-check to rule them out.

It seems like request() must be provided by classes using this trait. How about adding it as abstract method to this trait?
