According to the direct Logs, "Filter HTTP error page" corresponds to "Application Hiding" Medium the waf Policies. Uncheck it and let the customer test it again, and the business can be used normally.

solution

Uncheck "Hide Application Hiding" in waf

Suggestions and Conclusion

HTTP hiding can hide the field Info returned by the HTTP server message header, replace the server error page, and replace the request error page.
This case is just to express that the corresponding "filtering HTTP error pages" should adjust the "Application Hiding" Medium the waf Policies.
