## Retrieving errors


Typically, you want your application to check whether a request generated an error before you spend any time processing results. The easiest way to find out if an error occurred is to look for an `Error` node in the response from the Amazon RDS API.

XPath syntax provides a simple way to search for the presence of an `Error` node. It also provides a relatively easy way to retrieve the error code and message. The following code snippet uses Perl and the XML::XPath module to determine if an error occurred during a request. If an error occurred, the code prints the first error code and message in the response. 

```
use XML::XPath; 
    my $xp = XML::XPath->new(xml =>$response); 
    if ( $xp->find("//Error") ) 
    {print "There was an error processing your request:\n", " Error code: ",
    $xp->findvalue("//Error[1]/Code"), "\n", " ",
    $xp->findvalue("//Error[1]/Message"), "\n\n"; }
```

## Troubleshooting tips


 We recommend the following processes to diagnose and resolve problems with the Amazon RDS API:
+ Verify that Amazon RDS is operating normally in the AWS Region that you're targeting by checking [http://status.aws.amazon.com](http://status.aws.amazon.com/).
+ Check the structure of your request.

  Each Amazon RDS operation has a reference page in the *Amazon RDS API Reference*. Double-check that you are using parameters correctly. For ideas about what might be wrong, look at the sample requests or user scenarios to see if those examples do similar operations.
+ Check AWS re:Post.

  Amazon RDS has a development community where you can search for solutions to problems others have experienced along the way. To view the topics, go to [AWS re:Post](https://repost.aws/).
