Calling my .SVC which is hosted inside Azure App Service using Https will return "http 404"

0

I am working on a remote event receiver inside our sharepoint online root site collection (i am following the steps in this link https://derekgusoff.wordpress.com/2017/11/08/remote-event-receivers-youre-all-doing-it-wrong/), which worked well locally since i use http, but when i deploy it to azure it did not have any effect. here are the steps i followed for the deployment:-

  1. i generate the client and secret id, using this url https://****.sharepoint.com/_layouts/15/appregnew.aspx

  2. then i access the app from the SP admin center @ https://***-admin.sharepoint.com/_layouts/15/appinv.aspx

  3. i add the following inside the app permission:-

<AppPermissionRequests AllowAppOnlyPolicy="true">
 <AppPermissionRequest Scope="http://sharepoint/content/tenant" Right="FullControl" />
</AppPermissionRequests>
  1. inside VS 2019 >> i added the client id and client secret inside web.config >> i publish the project to my c drive. enter image description here

  2. then i zip the generated files "bin.zip".

  3. i created a new web app inside azure named TGroupPUSRER, as follow:- enter image description here

  4. after that i publish the zip file to azue using this command:-

az webapp deployment source config-zip --resource-group "PUS" --name "TGroupPUSRER" --src "C:\pus\bin.zip"

  1. i add the RER using these 2 command:-

Add-PnPEventReceiver -List "Project System" -Name "PUSRERupdating" -Url https://tgrouppusrer.azurewebsites.net/rer.svc -EventReceiverType ItemUpdating -Synchronization Synchronous

Add-PnPEventReceiver -List "Project System" -Name "PUSRERupdated" -Url https://tgrouppusrer.azurewebsites.net/rer.svc -EventReceiverType ItemUpdated -Synchronization Asynchronous

but when i edit items inside the Project System list the RER will not have any effect. so can anyone advice what i am missing? as i think i had done all the necessary steps for the RER to work.

I checked the logs and i can find the following exception, which is mentioning that mt rer.svc can not be found:-

System.Web.HttpException (0x80004005): The service '/api/vfs/site/wwwroot/RER.svc' does not exist. ---> System.ServiceModel.EndpointNotFoundException: The service '/api/vfs/site/wwwroot/RER.svc' does not exist. at System.ServiceModel.ServiceHostingEnvironment.HostingManager.EnsureServiceAvailable(String normalizedVirtualPath, EventTraceActivity eventTraceActivity) at System.ServiceModel.ServiceHostingEnvironment.EnsureServiceAvailableFast(String relativeVirtualPath, EventTraceActivity eventTraceActivity) at System.ServiceModel.Activation.HostedHttpRequestAsyncResult.HandleRequest() at System.ServiceModel.Activation.HostedHttpRequestAsyncResult.BeginRequest() at System.Runtime.AsyncResult.End[TAsyncResult](IAsyncResult result) at System.ServiceModel.Activation.HostedHttpRequestAsyncResult.End(IAsyncResult result)

although when i access the service from my browser @ https://tgrouppusrer.azurewebsites.net/rer.svc i got this page (hint the url i am providing has been truncated to remove real customer name ), which mean the srv does exists.:- enter image description here

now i enable the application logs for the azure web app >> and once i update a list item the application logs will show this error :-

The default timeout is 2 hours. Change the timeout with the App Setting SCM_LOGSTREAM_TIMEOUT (in seconds).<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><title>IIS Detailed Error - 404.0 - Not Found</title><style type="text/css"><!--body{margin:0;font-size:.7em;font-family:Verdana,Arial,Helvetica,sans-serif;}code{margin:0;color:#006600;font-size:1.1em;font-weight:bold;}.config_source code{font-size:.8em;color:#000000;}pre{margin:0;font-size:1.4em;word-wrap:break-word;}ul,ol{margin:10px 0 10px 5px;}ul.first,ol.first{margin-}fieldset{padding:0 15px 10px 15px;word-break:break-all;}.summary-container fieldset{padding-bottom:5px;margin-}legend.no-expand-all{padding:2px 15px 4px 10px;margin:0 0 0 -12px;}legend{color:#333333;;margin:4px 0 8px -12px;_margin-font-weight:bold;font-size:1em;}a:link,a:visited{color:#007EFF;font-weight:bold;}a:hover{text-decoration:none;}h1{font-size:2.4em;margin:0;color:#FFF;}h2{font-size:1.7em;margin:0;color:#CC0000;}h3{font-size:1.4em;margin:10px 0 0 0;color:#CC0000;}h4{font-size:1.2em;margin:10px 0 5px 0;}#header{width:96%;margin:0 0 0 0;padding:6px 2% 6px 2%;font-family:"trebuchet MS",Verdana,sans-serif;color:#FFF;background-color:#5C87B2;}#content{margin:0 0 0 2%;;}.summary-container,.content-container{background:#FFF;width:96%;margin-padding:10px;;}.content-container p{margin:0 0 10px 0;}#details-left{width:35%;float:left;margin-right:2%;}#details-right{width:63%;float:left;}#server_version{width:96%;_height:1px;min-height:1px;margin:0 0 5px 0;padding:11px 2% 8px 2%;color:#FFFFFF;background-color:#5A7FA5;border-bottom:1px solid #C1CFDD;border-font-weight:normal;font-size:1em;color:#FFF;text-align:right;}#server_version p{margin:5px 0;}table{margin:4px 0 4px 0;width:100%;border:none;}td,th{vertical-align:top;padding:3px 0;text-align:left;font-weight:normal;border:none;}th{width:30%;text-align:right;padding-right:2%;font-weight:bold;}thead th{background-color:#ebebeb;width:25%;}#details-right th{width:20%;}table tr.alt td,table tr.alt th{}.highlight-code{color:#CC0000;font-weight:bold;font-style:italic;}.clear{clear:both;}.preferred{padding:0 5px 2px 5px;font-weight:normal;background:#006633;color:#FFF;font-size:.8em;}--></style>

Here is a screen shot of the above error when i save it a html:- enter image description here

I found an important note, is that if i register the Remote Event Receiver using http instead of https, as follow:-

Add-PnPEventReceiver -List "Project System" -Name "PUSRERupdating" -Url http://tgrouppusrer.azurewebsites.net/rer.svc -EventReceiverType ItemUpdating -Synchronization Synchronous
Add-PnPEventReceiver -List "Project System" -Name "PUSRERupdated" -Url http://tgrouppusrer.azurewebsites.net/rer.svc -EventReceiverType ItemUpdated -Synchronization Asynchronous

the Remote Event Receiver will work well... so can this give an indication what is the problem.

c#
asp.net
azure
sharepoint
web-config
