MongoDB 7.0.12 and cant' read from Secondary

[Vkutovoy92]

Hi!
I have this config

    {ok, _MasterPID} = mongo_api:connect(
        Seed,
        Hosts,
        [{register, ?MASTER},  {max_overflow, MaxOverMaster}, {pool_size, PoolSizeMaster}, {rp_mode, primaryPreferred}],
        [{database, Database}, {auth_source, AuthSource}| Credentials]
    ),
    PoolSizeSlave  = proplists:get_value(pool_size_slave, Config),
    {ok, _SlavePID} = mongo_api:connect(
        Seed,
        Hosts,
        [{register, ?SLAVE}, {pool_size, PoolSizeSlave}, {rp_mode, secondaryPreferred}],
        [{database, Database}, {auth_source, AuthSource}, {r_mode, slave_ok} | Credentials]
    ),

It works fine when I write and read from master, but the errors appears when I try to read from Secondary

What am I doing incorrect?
