There are two failing test suites with this change, care to take a look?

[dblock]

Hmmm, this seems like a workaround around a workaround. I see a lot of code like this

Feels like a fix should be somewhere deeper.

What are the state(s) of your environment variables OPENSEARCH_INITIAL_ADMIN_PASSWORD and OPENSEARCH_PASSWORD that causes a local run to fail?

[nokados]

To reproduce the issue, just follow the DEVELOPER_GUIDE.

So, in the local environment, OPENSEARCH_PASSWORD may be set. OPENSEARCH_INITIAL_ADMIN_PASSWORD is for integration tests.

I’m currently unable to dedicate time to explore a deeper solution. At the moment, the code isn’t working as intended. If the extra two lines in the tests feel unnecessary to you, you’re welcome to refactor it, but unfortunately, I won’t be able to take that on right now.

Thanks for your help so far @nokados.
