Steps to Reproduce

Using the following function definitions:

  override fun getSecretManager(): SecretsManagerClient {
    return SecretsManagerClient {
      logMode = LogMode.LogRequestWithBody + LogMode.LogResponseWithBody
      region = System.getenv("AWS_REGION")
      credentialsProvider = EnvironmentCredentialsProvider()
      endpointProvider = object : SecretsManagerEndpointProvider {
        override suspend fun resolveEndpoint(params: SecretsManagerEndpointParameters): Endpoint {
          return Endpoint(uri = "https://secretsmanager.$region.amazonaws.com")
        }
      }
    }
  }
  
private suspend fun getDatabaseSecret(secretArn: String): DatabaseSecret {
    log.info { "Secret: $secretArn" } // This logs the correct secret
    val secret = appComponent.getSecretManager().use { client ->
      val secretJson = client.getSecretValue {
        GetSecretValueRequest {
          secretId = secretArn
        }
      }
      log.info { "Secret: $secretJson" }
      Json.decodeFromString<DatabaseSecret>(secretJson.secretString!!)
    }
    return secret
  }

Possible Solution

Unknown

Context

The lambda runs in an isolated VPC and has the purpose connect to RDS and execute schema changes.
I setup the connection between the lambda and a vpc endpoint allowing connection to secret manager.

The empty JSON body {} at the end of your request log suggests that a null secretId is being configured on the request or not being sent some other way.

Can you confirm that the secretArn you're using is never null? I see in your code sample it's a non-null String, but would like to make sure

[niqo01]

Thank you for looking into this.
You can see in the code above that I added a log the secretArn and I can confirm it contains a non null value and the correct secret arn.

I'm unable to reproduce this issue. I can successfully invoke GetSecretValue and most importantly, I see that my request has a non-empty body:

The fact that your request has an empty body {} strongly suggests you did send a request with a null secretId... I can't think of another reason this would fail for you.

Are you able to consistently reproduce this issue, can you provide a minimal reproduction?
