EventBridge putRule/PutRuleCommand: ERROR ValidationException: 1 validation error detected: Value 'aws.partner/sellingpartnerapi.amazon.com/121212121212/amzn1.sp.solution.cb4023df-4e06-4fcf-a8a4-123e3a6544ee' at 'eventBusName' failed to satisfy constraint: Member must satisfy regular expression pattern: [\.\-_A-Za-z0-9]+

Describe the bug

I got the error below when calling either aws-sdks putRule function or @aws-sdk/client-eventBridge's PutRuleCommand instance, in AWS lambda Node20.x runtime environment. Despite adhering to what seems to be the correct format, I received a validation error related to the eventBusName parameter.

Error:

ERROR ValidationException: 1 validation error detected: 
Value 'aws.partner/sellingpartnerapi.amazon.com/121212121212/amzn1.sp.solution.cb4023df-4e06-4fcf-a8a4-123e3a6544ee' 
at 'eventBusName' failed to satisfy constraint: Member must satisfy regular expression pattern: [\.\-_A-Za-z0-9]+

Expected Behavior

Creating an Event Rule without any errors as per Amazon Seller Partner API documentation As well as putRule function documentation

Current Behavior

The error is triggered when using aws-sdk putRule function Indicating a failure to satisfy the regular expression pattern for the eventBusName parameter.

The official AWS documentation for the putRule function specifies the following pattern for EventBusName parameter (arn:aws[\w-]*:events:[a-z]{2}-[a-z]+-[\w-]+:[0-9]{12}:event-bus\/)?[/\.\-_A-Za-z0-9]+

However, I believe the correct pattern should be: (arn:aws[\w-]*:events:[a-z]{2}-[a-z]+-[\w-]+:[0-9]{12}:event-bus\/)?[\/\.\-_A-Za-z0-9]+

But the error I get is different, it mentions that it should satisfy this expression: [\.\-_A-Za-z0-9]+

Both the event bus arn and the event bus name were used and they both result in the same error.

Reproduction Steps

Follow the steps in the SP-API documentation to create a destination and an event bus in your AWS. Set up notifications (Amazon EventBridge workflow

Using aws-sdk

  const eventPattern = {
    source: [{ prefix: "aws.partner/sellingpartnerapi.amazon.com" }],
    "detail-type": [
         "LISTINGS_ITEM_STATUS_CHANGE",
         "LISTINGS_ITEM_ISSUES_CHANGE"
    ],
  };

 const busName = "aws.partner/sellingpartnerapi.amazon.com/{aws_account}/amzn1.sp.solution.cb4023df-4e06-4fcf-a8a4-123e3a6544ee"

 const eventBus: CreateEventBusResponse = await eventBridge
    .createEventBus({
      EventSourceName: busName,
      Name: busName,
    })
    .promise();

  const rule: PutRuleResponse = await eventBridge
    .putRule({
      Name: "ruleName",
      EventBusName: eventBus.EventBusArn, // Or we can use `busName`
      State: "ENABLED",
      EventPattern: JSON.stringify(eventPattern),
    })
    .promise();

Using @aws-sdk/client-eventbridge

...
const client = new EventBridgeClient({ region: ensureEnv("AWS_REGION") }); // replace "REGION" with your AWS region

  const command = new PutRuleCommand({
    Name: "ruleName",
    EventBusName:  "aws.partner/sellingpartnerapi.amazon.com/{aws_account}/amzn1.sp.solution.cb4023df-4e06-4fcf-a8a4-123e3a6544ee",
    State: "ENABLED",
    EventPattern: JSON.stringify(eventPattern),
  });

 await client.send(command);

Possible Solution

I am aware that there has been a similar issue with Serverless, and it has been resolved. You can find more information about the resolution at https://github.com/serverless/serverless/issues/6594.
