We're getting below error when ingesting data:

Storage Error: More than one request trying to add/update/delete one edge/vertex at the same time.

Any idea how to fix this error?

Using Python library to ingest data.

`
config = Config()
config.max_connection_pool_size = 1

ok = connection_pool.init([('10.155.51.233', 9669)], config)        
 session = connection_pool.get_session('root', 'nebula')

`

Did you use the same session instance with multiple threads? The session is not thread-safe.

• Today, we used Nebula-Importer
• We followed the docs from here https://docs.nebula-graph.io/2.6.1/nebula-importer/use-importer/
• We could repro the error using Nebula-Importer (attached is the screen capture)

It seems you are inserting the same edge with 2 different sessions. Is this intended? Please check the data input source if this is not.

There is no more info about this issue. I will close it first, and you can reopen anytime it if needed. Thanks.
