@Dimonye0531 Could you please post the specific error log of Milvus? Additionally, you can run this script (https://github.com/milvus-io/pymilvus/blob/master/examples/simple.py) to check if the Milvus server is functioning properly.

[Dimonye0531]

I don't find any Milvus Error log. Logs contain all information from the request to respose.

There is the simple.py results:

Milvus Logs:
Milvus Logs.txt

semantic-router Logs:
semantic-router Logs.txt

I instll Milvus with this Method.
`
Step 1: wget https://github.com/milvus-io/milvus/releases/download/v2.6.4/milvus-standalone-docker-compose.yml -O docker-compose.yml

Step 2: sudo docker compose up -d
`
pymilvus version is 2.6.4

@JackLCL Please help look it.

[JackLCL]

@Dimonye0531 It seems that Milvus is running normally. Has the issue been resolved? If the issue remains unresolved, please provide detailed reproduction steps.

[Dimonye0531]

I think you misread the question, Don't Milvus is Err, The error is when the semantic-router write chche to Milvus . I couldn't find the missing field from the source code or the error info.

ERR:
adding pending request to chache: filed to upsert cahce entry :field does not exist in collection semantic_cache

my semantic_cache collection fields:

fields = [
FieldSchema(name="id", dtype=DataType.VARCHAR,max_length=64, is_primary=True),
FieldSchema(name="request_id", dtype=DataType.VARCHAR, max_length=64),
FieldSchema(name="model", dtype=DataType.VARCHAR, max_length=256),
FieldSchema(name="query", dtype=DataType.VARCHAR, max_length=65535),
FieldSchema(name="request_body", dtype=DataType.VARCHAR, max_length=65535),
FieldSchema(name="response_body", dtype=DataType.VARCHAR, max_length=65535),
FieldSchema(name="embedding", dtype=DataType.FLOAT_VECTOR, dim=384),
FieldSchema(name="timestamp", dtype=DataType.INT64),
]

Can you paste the complete error message? I'd like to see which field does not exist.

Also, you can use the logic of automatic collection creation in this project, then connect to Milvus using Attu(https://github.com/zilliztech/attu), check the specific collection schema, and compare it with the collection you created yourself to see the differences between the two.

[Dimonye0531]

IF report field does not exist i can fix it ,but that is all the err message.

Where is the Logic of automatic collection creation , please tell me, i don't find it ?
