Error Codes and Messages
Product Advertising API 5.0 errors provide information about syntactical errors in your requests, as well as errors that occur during the execution of your request; for example, a search for products returns no results.
Errors are composed of two elements:
Code
The error code is a unique string that identifies the error.
Message
The error message is a human-readable description of the error to help you debug the issue.
These elements will be nested within an Error element. If a request generates more than one error, all Errors will appear in the response.
Errors may appear at different levels in your response. But all the errors will be summarised as a top level attribute in the JSON response. The error will be represented as a list and each error will have the details about the error which occurred while executing the request. For more information, refer Error Messages.
