[lenguyenphuhuuo]

Current Behavior

When I run

 milvus-backup create -n selling_test_collection_demo_05 -a {'content': ['company_590']} --config selling-stage_milvus_config.yaml

We get this error

@lenguyenphuhuuo the parameter is a json. try like this:

milvus-backup create -n selling_test_collection_demo_05 -a "{\"content\":[\"company_590\"]}"
