Please check sys_configs_prefix and sys_configs. Did you set it to /?

"init_data_prefix" : "/lustre/ISSP2/bqcao/mqin/Dpgen/test/Initial",
"init_data_sys": [
"initset/deepmd"
],
"sys_configs_prefix": "/lustre/ISSP2/bqcao/mqin/Dpgen/test/Exploration",
"sys_configs": [
"configs/POSCAR"
],

here

"sys_configs": [
"configs/POSCAR"
],

The correct one is

"sys_configs": [
[
"configs/POSCAR"
]
],
