Error instantiating SqsClient - Unable to load an HTTP implementation from any provider in the chain. You must declare a dependency on an appropriate HTTP implementation or pass in an SdkHttpClient explicitly to the client builder.

Hi,

I am trying to instantiate SqsClient in my Scala project. When I build the image and deploy it in the EKS cluster, I keep getting the following error:

software.amazon.awssdk.core.exception.SdkClientException: Unable to load an HTTP implementation from any provider in the chain. You must declare a dependency on an appropriate HTTP implementation or pass in an SdkHttpClient explicitly to the client builder.

I am testing my code in EKS cluster where Pods are configured with ServiceAccount. I verified the two AWS_ROLE_ARN and AWS_WEB_IDENTITY_TOKEN_FILE environment variables are populated with valid values. Expecting the authentication to take place using the web identity token. I tried various version of AWS SDK from 2.10.11 onwards. Currently using the 2.13.9.

I am trying to instantiate SqsClient as shown below:

         SqsClient.builder()
               .region(Region.US_EAST_1)
               .httpClient(ApacheHttpClient.builder().build())
              .build()

Going by some suggestions in the other forums, I tried to instantiate WebIdentityTokenFileCredentialsProvider explicitly:

         SqsClient.builder()
                      .region(Region.US_EAST_1)
                      .credentialsProvider(WebIdentityTokenFileCredentialsProvider.create())
                      .build()

Out sbt config:

libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.2.3"
libraryDependencies += "com.typesafe.scala-logging" %% "scala-logging" % "3.9.2"
libraryDependencies += "com.typesafe" % "config" % "1.3.3"
libraryDependencies += "software.amazon.awssdk" % "sqs" % "2.13.9"
//libraryDependencies += "software.amazon.awssdk" % "sts" % "2.13.9"

I have also tried to use the following in sbt which includes a libraries for various services:

libraryDependencies += "software.amazon.awssdk" % "aws-sdk-java" % "2.13.9"

Following is the exception stacktrace:

Hmm, that’s odd. Could you try setting the system property as follows?

 System.setProperty(SdkSystemSetting.SYNC_HTTP_SERVICE_IMPL.property(), "software.amazon.awssdk.http.apache.ApacheSdkHttpService");
