public String getErrorCode() {
        return this.errorCode;
    }
<p>
The error code for an error that prevented Amazon Macie from retrieving and processing information about the
bucket and the bucket's objects. If this value is ACCESS_DENIED, Macie doesn't have permission to retrieve the
information. For example, the bucket has a restrictive bucket policy and Amazon S3 denied the request. If this
value is null, Macie was able to retrieve and process the information.
