I raised a PR to update expired pem file as #44, but the integ-fail with the following errors -

I see the following logs in the tests.

integration_1  | [2023-02-14T01:11:21,183][INFO ][o.o.n.Node               ] [aba6720f09e5] version[2.5.0], pid[102], build[tar/b8a8b6c4d7fc7a7e32eb2cb68ecad8057a4636ad/2023-01-18T23:48:48.981786100Z], OS[Linux/5.15.0-1031-azure/amd64], JVM[Eclipse Adoptium/OpenJDK 64-Bit Server VM/17.0.5/17.0.5+8]

This corresponds to the following from OpenSearch:

https://github.com/opensearch-project/OpenSearch/blob/4dd0c5f00f6d21d3dbc29afcb2454d927ce7817f/server/src/main/java/org/opensearch/node/Node.java#L386-L389

So it appears that the current CI is using the latest version of OpenSearch and this plugin only supports 1.x. Resolving #36 will add support for 2.x. But, these tests should use consistent versions of OpenSearch rather than latest.

I believe the first fix will be to use a consistent version for the CI tests.
