[BUG] Cannot find module: Opensearch Error on node 18

[PaaPaul]

What is the bug?

I got a module not found error when using the package in lambda after upgrading node from 16 to 18

How can one reproduce the bug?

• Install package
• Use lambda Runtime: nodejs18.x
• Run Lambda function

What is the expected behavior?

No errors or warning

What is your host/environment?

node v18

Do you have any screenshots?

Want to try to add node 18 to CI?

@PaaPaul What does your index.mjs file look like?

@nhtruong, do not have any file in my repo named that. This only pops up when node is at 18.
