Hi All, I am trying to use s3 plugin for backup and restore, please find the details below 1. I have create IBM COS bucket which is s3 compatible and created access and secret key 2. I have added s3.client.default.endpoint to IBM S3 bucket endpoint in Elasticsearch.yaml 3. i have added s3.client.default.access\_key s3.client.default.secret\_key but while verifying the bucket, i am getting following issue `The AWS Access Key ID you provided does not exist in our records. (Service: Amazon S3; Status Code: 403; Error Code: InvalidAccessKeyId; S3 Extended Request ID: null)"` Can someone please suggest, what might be going wrong here? Am i missing on something or IBM COS is not supported with S3 plugin? JFYI - the ES is 3 node cluster hosted on k8s Thanks Pallavi C ---
