This topic explains how to address the issue of a request failing due to a JSON format error when submitting CommandArgs and Envs parameters in JSON format via an HTTP request.
If you submit the CommandArgs and Envs parameters in JSON format within the request body and there is a JSON format error, this may prevent the task from executing. Please verify that the JSON format in the request body is correct. Adding application/json as the Content-Type in the request header is crucial because the event bus will block requests with JSON syntax errors and return the error reason. It is highly recommended to set the correct Content-Type in the request header. To identify the specific error, you can check the event tracking records for the corresponding event bus using the SAE task template ID in the EventBridge console.
