Just a suggestion:

we can change the direct modification of the csv in the test to modifying the csv through the api to make sure the whole process is working correctly:

arcadia/tests/example-test.sh

Lines 482 to 487 in 00dd4b9

	info "7.6 update qa.csv to make sure it can be embedding"
	echo "newquestion,newanswer,,," >>pkg/documentloaders/testdata/qa.csv
	mc cp pkg/documentloaders/testdata/qa.csv arcadiatest/${bucket}/dataset/dataset-playground/v1/qa.csv
	mc tag set arcadiatest/${bucket}/dataset/dataset-playground/v1/qa.csv "object_type=QA"
	sleep 3
	kubectl annotate knowledgebase/knowledgebase-sample-pgvector -n arcadia "arcadia.kubeagi.k8s.com.cn/update-source-file-time=$(date)"
