Sample code: nxwitness-storage_sdk is not recognized.

Cross-platform--SDK: https: //nxvms.com/download/sdk downloaded "nxwitness-storage_sdk-4.1.0.31398-universal".
I ran build_samples.bat in the storage_sdk directory to build.

The build was done in the same way as nxwitness-metadata_sdk.
I placed the built ftp_storage_plugin.dll&test_storage_plugin.dll file in "C:\Program Files\Network Optix\Nx Witness\MediaServer\ plugins".

Then I restarted NxWitness, but the plugin is not recognized by NxWitness.

How can I make the plugin recognized?

Development environment

--Cmake version 3.19.0-rc1
--Windows10: Microsoft Visual Stadio 2019
--Meta VMS version = 4.1.0.31398. (Nxwitness-metadata_sdk-4.1.0.31398-universal.zip

    Hello Kaho,

    > Then I restarted NxWitness, but the plugin is not recognized by NxWitness.

    What does it mean? What does "is not recognized" look like?

    Set Server's logLevel setting to DEBUG in the mediaserver.conf file. Restart the Server.

    Search Server's log_file.log for "PluginManager" messages. Do you see any related to "ftp_storage_plugin" and "test_storage_plugin"? Could you share your log_file.log file with Google disk or something similar, please?

    Thank you for your reply.

    "is not recognized" means that it does not appear in the Plugins tab of the camera settings (see attached image).
    I think that "ftp_storage_plugin" and "test_storage_plugin" will displayed in the part where "sample_analytics_plugin" is displayed, is it correct?
    In the log, "ftp_storage_plugin" and "test_storage_plugin" are output as "succeeded", but they are not displayed in the plugin tab like "sample_analytics_plugin".

    >  Could you share your log_file.log file with Google disk or something similar, please?

    We're sorry, but due to company regulations, we can't share Google discs.
    Extract the logs related to "ftp_storage_plugin" and "test_storage_plugin" of "Plugin Manager" from "log_file.log" and send them.

    Hello Kaho,

    Thanks for the detailed response.

    > I think that "ftp_storage_plugin" and "test_storage_plugin" will displayed in the part where "sample_analytics_plugin" is displayed, is it correct?

    No, it's not. Only analytics plugin are shown in the Plugins tab of the camera settings, since analytics plugins are designated specifically for cameras.

    You can see all loaded plugins (including storage and video source plugins) via the /api/pluginInfo API function.

    Hello, Andrey.

    Thank you for answering.

    "ftp_storage_plugin" and "test_storage_plugin" did not appear in System Administration in the main menu. Is this correct? (See attached image)

    Also, is there a way to check "ftp_storage_plugin" and "test_storage_plugin" other than log output?
    For example, on the NxWitnessClient screen.

    Hi,

    > "ftp_storage_plugin" and "test_storage_plugin" did not appear in System Administration in the main menu. Is this correct? 

    Yes, that's correct.


    > is there a way to check "ftp_storage_plugin" and "test_storage_plugin" other than log output?

    Yes, there is. Invoke the ec2/pluginInfo Server's  Web API function.

    http://localhost:7001/ec2/pluginInfo

    Here is its output
