Error: F_JG231B/F_JG290D: Received Status Code 400

Issue

While sending an alert from HVR to an SNS topic, the alert fails with the following errors:

• F_JG231B: Operating System command failed with exit code 1.
• F_JX0025: httpreq command failed with exit-code 1 and error.
• F_JG290D: Received status code 400 (Bad Request).
• F_JG0602: The previous error occurred while invoking URL 'sns://…' with method 'POST', custom headers 'Content-Type: application/x-www-form-urlencoded', and a payload containing Action=Publish & TopicArn=… .fifo & Message=…
• F_JG0557: The previous error occurred during request POST.

Environment

• HVR versions earlier than 6.2.5/9
• Alerts configured to use an AWS SNS FIFO topic with an ARN that ends in .fifo.

Resolution

To resolve this issue:

1. Create a new standard SNS topic with an ARN that does not end with .fifo.
2. Update the HVR alert configuration to use the new topic.
3. Send a test alert to confirm successful delivery.

Alternatively, upgrade HVR to version 6.2.5/9 or later, then re-run the test alert.

Cause

AWS SNS FIFO topics require the following parameters for every publish request:

• MessageGroupId
• MessageDeduplicationId

HVR versions earlier than 6.2.5/9 do not include these parameters when sending alerts to FIFO topics. As a result, SNS rejects the request with an error.

HVR version 6.2.5/9 and later adds support for SNS FIFO topics. In these versions, hvralert automatically includes the required parameters.
