Missing relationship creation / update via API

Hello everyone!

I’m having some issues with the SuiteCRM API, specifically with relationships. I’m trying to create an account->Security Group association via SOAP API using the following code:

  $relationshipAccGroup = array(
        'session' => $session_id,
        'module_name' => 'Accounts',
        'module_id' => '231300c3-feef-6230-b4ac-567163682', //> Account uuid
        'link_field_name' => 'SecurityGroups', //> from vardef
        'related_ids' => array(
            'e8ae920c-fd0d-b8d5-0e14-5671630f8f20' //> Security Group uuid
        ),
        'name_value_list' => array(),
        'delete' => 0
    );
   

   // get result
    $relationshipAccResult = $client->call('set_relationship', $relationshipAccGroup);
   

While the result is

Create relationship |Accounts <=> SecurityGroups| Result >>

Array
(
    [created] => 1
    [failed] => 0
    [deleted] => 0
)

when a user logs into SuiteCRM the relationship is not shown (I’m an On:Demand user so no direct access to the DB to check whether it exists or not), and the get_entry_list call returns the following

Array
(
    [result_count] => 1
    [total_count] => 1
    [next_offset] => 1
    [entry_list] => Array
        (
            [0] => Array
                (
                    [id] => 231300c3-feef-6230-b4ac-5671636829b2
                    [module_name] => Accounts
                    [name_value_list] => Array
                        (
                            [0] => Array
                                (
                                    [name] => id
                                    [value] => 231300c3-feef-6230-b4ac-5671636829b2
                                )

                            [1] => Array
                                (
                                    [name] => name
                                    [value] => La Lanterna
                                )

                        )

                )

        )

    [relationship_list] => Array
        (
            [0] => Array
                (
                    [link_list] => Array
                        (
                        )

                )

        )

)

Am I doing something wrong? Any suggestion would be really appreciated!
