You can use property "links" in "objectscript.conn", to add some links to your projects, which you will be able to open quickly

  "objectscript.conn": {
    "active": true,
    "username": "_system",
    "password": "SYS",
    "ns": "MYAPP",
    "port": 52773,
    "links": {
      "MyApp": "http://${host}:${port}/csp/${namespace}/main.csp"
    }
  }

After this, you will get a new item in the menu shown by click on the status bar with connection info.

While you are working with JSON, I would recommend to not do it manually and use native JSON support, available since 2016.2 (2016.1 with notes).

So, you can do it just 

set json = {}.%FromJSON(str)

or

set json = {}.%FromJSON(stream)

and value will be available by

write json."Not  Working Example"

If you have a version with no native JSON support, look at this project

I don't see XML here, but for your examples, I would use Regex

    Set regex = ##class(%Regex.Matcher).%New("(""[^""]*""):\s(""[^""]*""|[^,]*)")     
    
    Set regex.Text = """Working Example"": xyz,"
    Write !,regex.Text,!
    If regex.Locate() {
      Write !?5,regex.Group(1)
      Write !?5,regex.Group(2)
    }
    Write !     
    
    Set regex.Text = """Not  Working Example"": ""x,  y"","
    Write !,regex.Text,!
    If regex.Locate() {
      Write !?5,regex.Group(1)
      Write !?5,regex.Group(2)
    }

And the output will be

"Working Example": xyz, 
     "Working Example"
     xyz

"Not  Working Example": "x,  y",
     "Not  Working Example"
     "x,  y"

The only way to get it worked with CSP files right now, is to configure isfs. In this case, you will edit any files only remotely, with no local files.
You need file with code-workspace extension and content like this.

{
"folders": {
"uri": "isfs://yourserver/csp/user?ns=USER&csp"
}
}

More details, on how to configure and work with isfs, in the documentation

And just a note, for one more issue. The description to method %JSONNew says, that I can pass JSON which will be imported to the just created object

/// Get an instance of an JSON enabled class.<br><br>
/// 
/// You may override this method to do custom processing (such as initializing
/// the object instance) before returning an instance of this class.
/// However, this method should not be called directly from user code.<br>
/// Arguments:<br>
///     dynamicObject is the dynamic object with thee values to be assigned to the new object.<br>
///     containerOref is the containing object instance when called from JSONImport.
ClassMethod %JSONNew(dynamicObject As %DynamicObject, containerOref As %RegisteredObject = "") As %RegisteredObject [ CodeMode = generator, GenerateAfter = %JSONGenerate, ServerOnly = 1 ]
{
    Quit ##class(%JSON.Generator).JSONNew(.%mode,.%class,.%property,.%method,.%parameter,.%codemode,.%code,.%classmodify,.%context)
}

But in fact, it does does nothing with it, and generated code, just returns new object

%JSONNew(dynamicObject,containerOref="") public {
  Quit ##class(Conduit.Model.User).%New()
}

Yeah, I know that I can do %FromJSON, but it looks like overhead, here.

Look at this article, you can generate API implementation just from swagger specification. It generates a bunch of methods for each call in swagger spec.

Something like this

/// Get an article. Auth not required<br/>
/// The method arguments hold values for:<br/>
///     slug, Slug of the article to get<br/>
ClassMethod GetArticle(slug As %String) As %DynamicObject
{
    //(Place business logic here)
    //Do ..%SetStatusCode(<HTTP_status_code>)
    //Do ..%SetHeader(<name>,<value>)
    //Quit (Place response here) ; response may be a string, stream or dynamic object
}

So, in this method, I would add code like this

/// Get an article. Auth not required<br/>
/// The method arguments hold values for:<br/>
///     slug, Slug of the article to get<br/>
ClassMethod GetArticle(slug As %String) As %DynamicObject
{
    Set article = ##class(Article).slugOpen(slug,, .tSC)
    If $$$ISERR(tSC) {
        Do ..%SetStatusCode(404)
        Return 
    }
    
    Return article
    #; Or
    Return article.%JSONExport()
}

But this will not work. The only ways to make to work is to return string or stream

Return article.%JSONExportToString()
Return article.%JSONExportToStream()

But, I have to wrap the output. And the best would be to get something like this

Return { "article": (article.%JSONExport()) }

While I have to write this, and hope do not get MAXSTRING error, for some cases

Return "{ ""article"": " _ article.%JSONExportToString() _ "}"

And it's just only a case with one object, while for some cases I have to return an array.

Definitely, something wrong in the configuration. Code in InterSystems in fact is no different from any other data stored there. So, you may have some wrong mappings, or store some of your code in %SYS. 

I have a configuration with mirroring + ECP, and it works perfectly, I don't even care which of the nodes is primary, and can switch it any time, with no issues. And I have even more than one Code databases, and more than 20 Data databases. Mirroring Nodes works on 2018.1 while ECP Application Servers on 2012.2, with no issues.

If you have some doubts about your configuration, you can ask for help through WRC, or we can help you with it, we can review your settings, and say what actually happened and how to solve it
