New test experiment MET_ensemble_verification_only_vx_time_lag can not be created due to invalid variable "NET"

[mkavulich]

Expected behavior

All WE2E tests should succeed, including MET_ensemble_verification_only_vx_time_lag

Current behavior

Since #828, the workflow creation script now fails when attempting to run this experiment:

Calling workflow generation function for test MET_ensemble_verification_only_vx_time_lag

FATAL ERROR:
