sorry there is not enough context here to debug your problem. Here is how to place good support requests

https://support.safe.com/hc/en-us/articles/25407438078349-How-to-Create-a-Great-FME-Form-Support-Case 

there is an attachment icon on these windows

FME Workspace file: test.zip, we created a published parameter named “测试”.

#include <isession.h>
#include <iworkspacerunner.h>
int main()
{
    IFMESession* session;
    FME_MsgNum err = FME_createSession(session);
    if (err)
    {
        return 0;
    }
    err = session->init(NULL);

    IFMEWorkspaceRunner* runner = session->createWorkspaceRunner();
    IFMEStringArray* array = session->createStringArray();
    IFMEString* str = session->createString();

    *str = "test.fmw";
    runner->getPublishedParamNames(*str, *array);

    for (size_t i = 0; i < array->entries(); i++)
    {
        std::string item = (*array)(i);
        printf("%s\n", item.c_str());
    }
    session->destroyString(str);
    session->destroyStringArray(array);
}

After resolving the workspace file, the parameter’s name will be “????”.

It’s probably worth also opening up a support case with Safe and linking this thread

yeap thats what I suggested in first response
