this 400 bad request not go through exception handler:
{ "message": "the request invalid.", "messagedetail": "the parameters dictionary contains null entry parameter 'subscriptionid' of non-nullable type 'system.guid' method 'system.net.http.httpresponsemessage get(system.guid)' in 'product.controllers.itemcontroller'. optional parameter must reference type, nullable type, or declared optional parameter." }
on webapiconfig.cs
have this:
config.services.replace(typeof(iexceptionhandler), new httpexceptionhandler());
every exception thrown action, repository, service layer levels handled exception handler. error , generic webapi exception handler kicks in.
how should fix in order exception go through exception handler?
i have same problem, here solution
1- add filter
public class requestnovalidoattribute : actionfilterattribute { public override void onactionexecuting(httpactioncontext actioncontext) { if (!actioncontext.modelstate.isvalid) { var response = new httpresponsemessage(httpstatuscode.badrequest) { requestmessage = actioncontext.request, content = new stringcontent("formato no vĂ¡lido.") }; actioncontext.response = response; } } }
2- add filter in webapiconfig.cs
config.filters.add(new requestnovalidoattribute());
