How to find in specific vector

I defined 2 custom vector in collcection, for example:
image and msg

When i try to find the vector in msg, i get error Bad Request.

This is how the code looks:

First i defined the settings vector:

await client.createCollection(collectionName, {
vectors: {
msg:{
size: 384,
distance: 'Cosine',
},
size: 4,
distance: 'Cosine',
},
optimizers_config: {
default_segment_number: 2,
},
replication_factor: 2,
});

Then i tried to search:

const res1 = await client.search(collectionName, {
vector: { "vector": { "vector": [1.0, 2.0, 3.0], "name": "msg" } },
limit: 3,
});

Start at the client.search call and compare its vector argument with the preceding createCollection configuration for the named msg vector. Reproduce the Bad Request using the shown collection and search inputs, then confirm that searching the specific vector succeeds without an error.
