[Bug]: [GoSDK] After loading a collection asynchronously, querying it immediately returns a bad msg

[ThreadDao]

Is there an existing issue for this?

Environment

- Milvus version: master-20241118-12ed40e1-amd64
- Deployment mode(standalone or cluster):
- MQ type(rocksmq, pulsar or kafka):    
- SDK version(e.g. pymilvus v2.0.0rc2): go sdk v2
- OS(Ubuntu or CentOS): 
- CPU/Memory: 
- GPU:

Current Behavior

1. collection fields: int64, floatVector, enable dynamic field
2. load collection asynchronously and skip dynamic field
3. query immediately but gets an error message that is not instructive.

_, err = mc.LoadCollection(ctx, clientv2.NewLoadCollectionOption(schema.CollectionName).WithSkipLoadDynamicField(true))
common.CheckErr(t, err, true)
// err = loadTask.Await(ctx)
// common.CheckErr(t, err, true)

// search and verify output dynamic fields
	_, err = mc.Query(ctx, clientv2.NewQueryOption(schema.CollectionName).WithOutputFields(common.DefaultDynamicNumberField).WithLimit(10))
	common.CheckErr(t, err, false, fmt.Sprintf("field %s cannot be returned since dynamic field not loaded", common.DefaultDynamicNumberField))

Steps To Reproduce

func TestLoadSkipDynamicField(t *testing.T) {
	/*
		1. release and reload with skip load dynamic field=true
		2. search on dynamic field in expr and/or output_fields
	*/
	// create collection -> insert -> flush -> index
	ctx := hp.CreateContext(t, time.Second*common.DefaultTimeout)
	mc := createDefaultMilvusClient(ctx, t)

	// create collection -> insert -> flush -> index -> load
	prepare, schema := hp.CollPrepare.CreateCollection(ctx, t, mc, hp.NewCreateCollectionParams(hp.Int64Vec), hp.TNewFieldsOption(), hp.TNewSchemaOption().TWithEnableDynamicField(true))
	prepare.InsertData(ctx, t, mc, hp.NewInsertParams(schema), hp.TNewDataOption())
	prepare.FlushData(ctx, t, mc, schema.CollectionName)
	prepare.CreateIndex(ctx, t, mc, hp.TNewIndexParams(schema))
	prepare.Load(ctx, t, mc, hp.NewLoadParams(schema.CollectionName))

	// query and verify output dynamic fields
	queryRes, err := mc.Query(ctx, clientv2.NewQueryOption(schema.CollectionName).WithOutputFields(common.DefaultDynamicFieldName).WithLimit(10))
	common.CheckErr(t, err, true)
	common.CheckOutputFields(t, []string{common.DefaultDynamicFieldName, common.DefaultInt64FieldName}, queryRes.Fields)

	// reload and skip dynamic field
	mc.ReleaseCollection(ctx, clientv2.NewReleaseCollectionOption(schema.CollectionName))
	_, err = mc.LoadCollection(ctx, clientv2.NewLoadCollectionOption(schema.CollectionName).WithSkipLoadDynamicField(true))
	common.CheckErr(t, err, true)
	// err = loadTask.Await(ctx)
	// common.CheckErr(t, err, true)

	// search and verify output dynamic fields
	_, err = mc.Query(ctx, clientv2.NewQueryOption(schema.CollectionName).WithOutputFields(common.DefaultDynamicNumberField).WithLimit(10))
	common.CheckErr(t, err, false, fmt.Sprintf("field %s cannot be returned since dynamic field not loaded", common.DefaultDynamicNumberField))

	_, err = mc.Query(ctx, clientv2.NewQueryOption(schema.CollectionName).WithFilter(fmt.Sprintf("%s > 0", common.DefaultDynamicNumberField)))
	common.CheckErr(t, err, false, "but dynamic field is not loaded")
}
