If I have a application gateway v2 sku waf_v2 with exclusion setup at WAF level

And run backend update 

            ApplicationGateway appGateway = azure.applicationGateways().getByResourceGroup(rgName, appGwName);                     
            final ApplicationGateway refreshedAppGateway = appGateway.refresh();            
            refreshedAppGateway.update()
                    .updateBackend(applicationGatewayBackend)
                    .withIPAddress("192.168.229.6")
                    .parent()

thanks @weidongxu-microsoft and @xccc-msft working to make another repo

ovidiu10 commented 3 years ago

the key issue is RequestHeaderNames with header "Referer" https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Referer 

.withExclusions(Arrays.asList(new ApplicationGatewayFirewallExclusion().withSelector("Referer")
                            .withMatchVariable("Equals").withMatchVariable("RequestHeaderNames"))))

I got same error even if I try to create the application gateway

webApplicationFirewallConfiguration.exclusions.selectorMatchOperator is required and cannot be null. java.lang.IllegalArgumentException: webApplicationFirewallConfiguration.exclusions.selectorMatchOperator is required and cannot be null

xseeseesee commented 3 years ago

After investigation, the swagger definition of ApplicationGatewayFirewallExclusion shows all properties are required here while the server only returns matchVariable if the exclusion rule is with Equals any and *. Add Service Attention so the service team could help check if they should update swagger or add missing properties in the response.

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @surajmb, @appgwsuppgithub.
