Expected Behavior

No response

Steps To Reproduce

1. create a collection, 8 fields: "id", "float_vector", "float_vector_1", "int64_1", "int64_2", "float_1", "double_1", "varchar_1"
2. build index
   IVF_FLAT: float_vector
   HNSW: float_vector_1
   INVERTED: "int64_1", "int64_2", "float_1", "double_1", "varchar_1"
3. insert 25m data
4. flush collection
5. build index again with the same params <- failed
