Describe the bug Release 1.2.0 breaks the example(s) in https://docs.chainlit.io/data-persistence/custom

To Reproduce

This is the code that works prior to 1.2.0

storage_client = S3StorageClient(bucket=bucket_name)
cl_data._data_layer = SQLAlchemyDataLayer(conninfo=db, storage_provider=storage_client)

After 1.2.0, on startup, I get the TypeError

2024-10-01 14:26:12 - S3StorageClient initialized
