It seems like $sqlWalker->walkUpdateStatement($AST) of type string is incompatible with the declared type string[] of property $sqlStatements.
                                                                                                                                                                                                                                                            

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Our type inference engine has found an assignment to a property that is incompatible
with the declared type of that property.


Either this assignment is in error or the assigned type should be added
to the documentation/type hint for that property..

The expression return $conn->executeUpd...ments, $params, $types) returns the type integer which is incompatible with the return type mandated by Doctrine\ORM\Query\Exec\...tSqlExecutor::execute() of Doctrine\DBAL\Driver\Statement.
                                                                                                                                                                                                                                                                                                                

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
In the issue above, the returned value is violating the contract defined by the
mentioned interface.


Let's take a look at an example:


interface HasName {
    /** @return string */
    public function getName();
}

class Name {
    public $name;
}

class User implements HasName {
    /** @return string|Name */
    public function getName() {
        return new Name('foo'); // This is a violation of the ``HasName`` interface
                                // which only allows a string value to be returned.
    }
}
