Exception authenticating MongoCredential{mechanism=MONGODB-AWS,

I am using AWS IAM for connecting with Mongodb in Java Springboot. I have added aws v2 auth SDK, but I'm getting auth failure error. In logs I can see it's trying to use IAM but not working.

Springboot config:

spring:
  autoconfigure:
    exclude: org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration
  data:
    mongodb:
      uri: ${RESOURCE_MONGODB_URL:mongodb://127.0.0.1:27017/ab?directConnection=true&serverSelectionTimeoutMS=2000&appName=mongosh+1.8.2}&authMechanism=MONGODB-AWS
      database: ${RESOURCE_MONGODB_NAME}

Logs:

Using DefaultCredentialsProvider from AWS SDK v2 to retrieve AWS credentials. This is the recommended configuration
