Ошибка hostname could not be parsed

I recently came across this issue. I tried to use the drive mapping workaround like @drwatson85 mentioned. This issue went away; however, I started encountering other issues. Odd issues.

The visual studio IDE compiler was not keeping up with my changes. Like i’ll add a public property on a class and i was unable to reference that property in another file. It was saying the property didn’t exist. I was able to do a compile just fine though.

Also the «Errors» window would not update when there was a valid compilation error. I removed a public static from a static class and it was properly failing the build, but the errors was not showing anything. I had to look at the output to see what was hte issue.

And finally, while debugging a unit test it would complain that the source was modified and i could either stop the debug or edit. I didn’t make any changes to the source file at all, and git was not detecting any code changes either.

These issues are in regards to Visual Studio 2019 Professional, version Version 16.10.0. Also these oddities were appeaing in our unit test project which had project references to the main code. The unit test project is using:

• NUnit 3.16.1
• NUnit3TestAdapter 3.16.1
• Microsoft.NET.Test.Sdk 16.5.0

It’s not a normal behavior.

If you look at the error message, you can see that problem is related to:

System.Uri.CreateThis(String uri, Boolean dontEscape, UriKind uriKind)

It meant that when any block tries to send request to Sitecore via SitecoreConnectionManager, and
SitecoreConnectionManager processes request via SitecoreConnectionManager.ProcessRequest and couldn’t create Uri:

SitecoreConnectionPolicy policy = commerceContext.GetPolicy<SitecoreConnectionPolicy>();
Uri address = new Uri(string.Format("https://{0}", (object) policy.Host));

From the first look it must works correctly, but…not…

Why do you see this error?

Commerce Engine OOTB has AdventureWorks, Habitat, any your custom environment(s) and … Global environment

Engine tries to send request and get any item from Sitecore, but commerceContext has Environment property which is set to GlobalEnvironment.

If you will open Global.json file you will see that SitecoreConnectionPolicy is missing for GlobalEnvironment and for sure policy.Host is equal null.

How to fix it?

You need to copy and paste configuration below to Global.json file to Policies list:

{
        "$type": "Sitecore.Commerce.Plugin.Management.SitecoreConnectionPolicy, Sitecore.Commerce.Plugin.Management",
        "Host": "{hostname.com}",
        "SitecoreDatabase": "master",
        "UserName": "admin",
        "Domain": "sitecore",
        "Password": "b",
        "ConnectionLeaseTimeout": 60000,
        "AuthRequestUrl": "sitecore/api/ssc/auth/login",
        "Protocol": "https"
}

You need to change Host, UserName, Password base on your configuration.
Also you can find your existing configuration in PlugIn.Content.PolicySet-1.0.0.json file and copy it to Global.json file.

After that you need to Bootstrap engine and restart apppool or iis.

This fix I checked on Sitecore Commerce 9 Update-1.

In Sitecore Commerce 9 Update-2 was added additional check:

        SitecoreConnectionPolicy policy = commerceContext.GetPolicy<SitecoreConnectionPolicy>();
        if (string.IsNullOrEmpty(policy?.Host))
        {
          commerceContext.Logger.LogError(string.Format("SitecoreConnectionManager: SitecoreConnectionPolicy for {0} is missing the host configuration", (object) commerceContext.Environment.Name), Array.Empty<object>());
          return (HttpResponseMessage) null;
        }
        Uri address = new Uri(string.Format("https://{0}", (object) policy.Host));

Which is more informative
