[BUG] index_not_found_exception is thrown intermittently

[Abhisha1]

What is the bug?

I am working with Amazon OpenSearch Serverless and have noticed the index_not_found_exception getting thrown when I try to create and index intermittently, and sometimes when I try a bulk operation.

How can one reproduce the bug?

The error pops up somewhat randomly but here are the two scenarios I've seen the bug

1. Check if index exists
2. Create index (it can fail here)
3. Create a bulk operation which inserts data (it can fail here)

What is the expected behavior?

The index should be created or the data inserted

What is your host/environment?

OpenSearch Serverless

Do you have any screenshots?

Do you have any additional context?

Add any other context about the problem.

@Abhisha1 This looks like a problem with serverless specifically, have you opened a support ticket with AWS yet?

[Abhisha1]

Ahh I see, wasn't sure what the best place was. I will raise a support ticket there in that case. Thanks @dblock

@Abhisha1 , It looks like you are using Index UUID to check if index exists, did you try with Index name ?
