Current Behavior

I am trying to create a new collection locally with a custom schema but it is throwing up a MAX len not found error.

pymilvus.exceptions.MilvusException: <MilvusException: (code=2000, message=Assert "type_map.count(MAX_LENGTH)" at /Users/zilliz/milvus-lite/thirdparty/milvus/internal/core/src/common/Schema.cpp:70

Expected Behavior

Steps To Reproduce

Using the following code:

from pymilvus import (
    connections,
    utility,
    FieldSchema,
    CollectionSchema,
    DataType,
    Collection,
    MilvusClient
)

milvus_client = MilvusClient(f"pdf_para.db" )

collection_name = "test_schema"

has_collection = milvus_client.has_collection(collection_name, timeout=5)
if has_collection:
    milvus_client.drop_collection(collection_name)

schema = milvus_client.create_schema(enable_dynamic_field=True)

schema.add_field(field_name="paragraph_id", datatype=DataType.VARCHAR,  max_length=65,is_primary = True, auto_id = False)
schema.add_field(field_name="embeddings", datatype=DataType.FLOAT_VECTOR, dim=512)
schema.add_field(field_name = "text",datatype=DataType.STRING )
schema.add_field(field_name = "file",datatype=DataType.STRING)

index_params = milvus_client.prepare_index_params()

index_params.add_index(
    field_name="embeddings",
    metric_type="COSINE",
    index_type="IVF_FLAT",
    index_name="vector_index",
)
milvus_client.create_collection(collection_name, schema=schema, index_params=index_params, consistency_level="Strong", )
