XMLThreatProtection 政策

This section describes the fault codes and error messages that are returned and fault variables that are set by Edge when this policy triggers an error. This information is important to know if you are developing fault rules to handle faults. To learn more, see What you need to know about policy errors and Handling faults.

Runtime errors

These errors can occur when the policy executes.

Notes:

• The error name ExecutionFailed is the default error name and will be returned regardless of the type of error detected; however, this default can be changed by setting an organization-level property. When this property is set, the error name will reflect the actual error. For example, "TextExceeded" or "AttrValueExceeded". See Usage Notes for details.
• The 500 HTTP status is the default; however, the HTTP Status can be changed to 400 for request flow faults by setting an organization-level property. See Usage Notes for details.

Deployment errors

None.

Fault variables

These variables are set when a runtime error occurs. For more information, see What you need to know about policy errors.

Example error response

{
  "fault": {
    "faultstring": "XMLThreatProtection[XPT-SecureRequest]: Execution failed. reason: XMLThreatProtection[XTP-SecureRequest]: Exceeded object entry name length at line 2",
    "detail": {
