Error on SAP Adapter receiving port

Question

Hello

We are trying to setup a new BizTalk 2020 POC. But we are having some problems on the SAP adapter.

When I start the receiving port it crashes immediatlly with the next error:

The Messaging Engine failed to add a receive location "From SAP-ERP IDOC WCF-SAP" with URL "sap://Client=100;Lang=NL;@d/SAP_ERP_SERVER/?ListenerDest=SAP_ERP_IN" to the adapter "WCF-Custom". Reason: "Microsoft.ServiceModel.Channels.Common.ConnectionException: Access to the path 'ApplicationData\' is denied. ---> System.UnauthorizedAccessException: Access to the path 'ApplicationData\' is denied.

   at Microsoft.BizTalk.Adapter.Wcf.Runtime.WcfReceiver`2.AddReceiveEndpoint(String url, IPropertyBag adapterConfig, IPropertyBag bizTalkConfig)".

I think somebody made a fault in the SAP adapter. It think  somebody wrote something like this

 

 Directory.CreateDirectory(Environment.SpecialFolder.ApplicationData.ToString());

But it should have been this

 Directory.CreateDirectory(Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData.ToString()));

Kind regards
