AWS SNS error - Invalid parameter while publishing message using aws-cli

Question

I am working with AWS SNS services and completed the initial setup as the AWS documentation. I just needed to test it using aws-cli. So I used the following command to publish a test message to SNS topic from my local PC.

aws sns publish --topic-arn "arn:aws:sns:us-east-1:xxxxxxxxxxx:test-notification-service" --message "Hello, from SNS"

However, I got stuck on the following generic error. It just says Invalid Parameter. I have configured the ~/.aws/credentials as needed.

An error occurred (InvalidParameter) when calling the Publish operation: Invalid parameter: TopicArn

what is you default region set to in AWS cli? It might be a issue due to cross region — Aatish Sai

The issue is due to cross-region. You AWS-CLI default region might be different to the region your SNS service location.

Check your AWS-CLI location and make sure you are in the same region as your SNS.

To check your region in AWS CLI use:

aws configure get region

To configure your AWS region you can use the command:

aws configure set region <region-name>

If anyone using aws-sdk in NodeJS is facing this error, then check whether every initialization of the SDK has the same value for region in its config property.

You can just add region parameter --region us-east-1 to your command:

aws sns publish --topic-arn "arn:aws:sns:us-east-1:xxxxxxxxxxx:test-notification-service" --message "Hello, from SNS" --region us-east-1

In my case, the setTopicArn didn't work.

From debugging, I've found the setTargetArn, use it and worked.

String content = fileName + ":" + percentage;

PublishRequest publishRequest = new PublishRequest();

publishRequest.setTargetArn(config.getTopicArn());
publishRequest.setMessage(content);
publishRequest.setSubject("Resize");

snsClient.publish(publishRequest);

I'm using springboot and aws sdk

<dependency>
    <groupId>com.amazonaws</groupId>
    <artifactId>aws-java-sdk-sns</artifactId>
    <version>1.12.772</version>
</dependency>
