Amazon Simple Notification Service (SNS) is a fully managed push messaging service that allows you to send notifications from the cloud to subscribing endpoints or clients. It is commonly used for sending alerts, notifications, and updates to users or systems in a scalable and cost-effective manner.
When using AWS SNS, you might encounter the InvalidParameter
error. This error indicates that there is an issue with one or more parameters in your request. It can prevent your notifications from being sent successfully.
The error message typically looks like this:
{"Error": {"Code": "InvalidParameter", "Message": "The request contains an invalid parameter value."}}
The InvalidParameter
error occurs when the parameters provided in the SNS request do not meet the expected format or constraints. This can happen due to incorrect data types, missing required parameters, or values that exceed allowed limits.
To resolve the InvalidParameter
error, follow these steps:
Ensure that all parameter names in your request match the expected names as defined in the AWS SNS API documentation. Double-check for any typos or incorrect casing.
Review the values of each parameter to ensure they meet the required format and constraints. For example, if a parameter expects a string, ensure you are not providing a number.
Make sure all required parameters are included in your request. Refer to the SNS Publish API reference to identify mandatory parameters.
Check if any parameters exceed the allowed size or value limits. For example, the message size should not exceed 256 KB.
By carefully reviewing and correcting the parameters in your AWS SNS request, you can resolve the InvalidParameter
error and ensure your notifications are sent successfully. For further assistance, consult the AWS Support Knowledge Center.
