The AddGlobalFields function fails after using the integrated zap component zapx as a writer

[smx-Morgan]

The AddGlobalFields function failed to set the global value after using zero contrib
This is my code, written based on example. (If zapx is not used as a writer, the global value will be corrected)

The obtained result does not have a global value
The case of zapx does not include AddGlobalFields. How can I set the global feild using zapx？
