Got errors:

F0617 14:33:56.501129 4170258 generator.go:384] ERROR Generating GoStruct Code: path "/openconfig-network-instance/network-instances/network-instance/protocols/protocol/isis/interfaces/interface/weighted-ecmp/config/load-balancing-weight": default value not supported for wrapper union values, please generate using simplified union leaves

Is it a bug ? (Maybe releate to #582 #613 #961 )

This was due to a feature addition for union leaf defaults some time ago.

Are you able to modify your downstream code to use the flag generate_simple_unions?

The recommended list of enum flags to use is

 -shorten_enum_leaf_names \ 
 -trim_enum_openconfig_prefix \ 
 -typedef_enum_with_defmod \ 
 -enum_suffix_for_simple_union_enums \ 
 -generate_simple_unions \
