Guidance on how to use AWSAssumeRoleCredentialsProvider

[mt-rpranata]

Hi,

We are using io.confluent.connect.s3.S3SinkConnector from kafka-connect-s3:5.5.3 installed by

confluent-hub install --no-prompt confluentinc/kafka-connect-s3:5.5.3

We have been trying to use AWSAssumeRoleCredentialsProvider with s3.credentials.provider.class. We followed the guide at https://docs.confluent.io/5.5.1/connect/kafka-connect-s3/index.html

    "s3.credentials.provider.class": "AWSAssumeRoleCredentialsProvider",
    "sts.role.arn": "arn:aws:iam::111111111111:role/service-role/SinkerRole",
    "sts.role.external.id": "external-id",
    "sts.role.session.name": "session-name",

However, when we send the REST request we got this

{"error_code":400,"message":"Connector configuration is invalid and contains the following 2 error(s):\nInvalid value AWSAssumeRoleCredentialsProvider for configuration s3.credentials.provider.class: Class AWSAssumeRoleCredentialsProvider could not be found.\nInvalid value null for configuration s3.credentials.provider.class: Class must extend: interface com.amazonaws.auth.AWSCredentialsProvider\nYou can also find the above list of errors at the endpoint /connector-plugins/{connectorType}/config/validate"}

However, when we use com.amazonaws.auth.DefaultAWSCredentialsProviderChain

We thought that #366 could be a related issue but no luck.

I made a fool of myself.

- "s3.credentials.provider.class": "AWSAssumeRoleCredentialsProvider",
+ "s3.credentials.provider.class": "AwsAssumeRoleCredentialsProvider",

And I am having the same issues with #366 now that throw an exception caused by blank sts.role.external.id

Caused by: org.apache.kafka.common.config.ConfigException: Missing required configuration "sts.role.external.id" which has no default value.

Thank you!
