@RyanL1997 I fixed an testing running forever issue recently for observability, and I noticed two tests are failing for 7_datasources_dashboard.spec.js: https://github.com/opensearch-project/opensearch-dashboards-functional-test/actions/runs/7712151209/job/21019043851?pr=1023

Could you take a look?

@ruanyl I can take a look on this. This is due to the enable of security, so that the url has the slug of security tenant.

Hi @ruanyl, thx for the reminder. I have fixed the issue. Could you please verify that?

@RyanL1997 thanks for the fix! Btw, maybe you want to create another PR to apply the same fix to main :)
