-----------------------------
Summary: aws2-sqs: Polling fails because of "host must not be null"
Key: CAMEL-14979
URL: https://issues.apache.org/jira/browse/CAMEL-14979
Project: Camel
Issue Type: Bug
Components: camel-aws2
Affects Versions: 3.2.0, 3.1.0
Reporter: Jan S
Attachments: aws2-sqs-example.zip
First of all: I attached a demo-project to the issue to reproduce the problem.
What am I doing:
Polling messages from AWS-SQS FIFO queues in a spring-boot 2 environment with
java 11, using camel-aws2-sqs-starter.
I started with version 3.0.1 and the aws-sqs component, the configuration was
fine, up and running.
Since I switched to camel 3.1.0/3.2.0 and aws2-sqs component I receive the
following error:
{code:java}
Caused by: [software.amazon.awssdk.core.exception.SdkClientException - Unable
to marshall request to JSON: host must not be
null.]software.amazon.awssdk.core.exception.SdkClientException: Unable to

I tried to find solutions using
[https://camel.apache.org/camel-spring-boot/latest/aws2-sqs-starter.html] and
had a short chat with [~acosentino].
For the demo project to run you'll need to fill in
"camel.component.aws2-sqs.access-key", "camel.component.aws2-sqs.secret-key"
and a ARN "com.example.arn" of your FIFO-queue. All keys are found in the
application.properties file.
