Yes, when you created a new class, it is just a file on your local disk. When you saved it, VSCode caught this action, and sent it to the server, and compiled it. But deleting this file, not a reason to do the same on the server.

You can delete class with Explorer view, there you may find any classes, that are stored on the server. By context menu you can Delete the item on the server, or Export it to get the local version. Icons close to class names, the same as in File Explorer view, may indicate the connection to your local file.

github.dev, is just a simple VSCode but in the cloud. It may get a coloring if it would allow at least our main extensions for ObjectScript, which in fact provide a basic coloring. GitHub.com itself uses coloring from another source, which in fact almost the same as for VSCode.

I'll look at github.com, and maybe I will find a solution, how to get coloring there somehow. And thinking about Codespaces feature as well.

As I know, there is no way to have a schedule for the whole production. Just only services can have scheduled.

With working hours 8:00-18:00, will be something like this.

START:WEEK-*-01T08:00:00,STOP:WEEK-*-01T18:00:00,START:WEEK-*-02T08:00:00,STOP:WEEK-*-02T18:00:00,START:WEEK-*-03T08:00:00,STOP:WEEK-*-03T18:00:00,START:WEEK-*-04T08:00:00,STOP:WEEK-*-04T18:00:00,START:WEEK-*-05T08:00:00,STOP:WEEK-*-05T18:00:00

USER>set json = [0,1,2]                                                                                     

USER>set json = [0,1,2], iter = json.%GetIterator()

USER>while iter.%GetNext(.key, .val){ write !,"[",key,"]=",val do:key=0 json.%Remove(key) }

[0]=0
[1]=2
USER>zw json
json=[1,2]  ; <DYNAMIC ARRAY>

And even with %Remove will not reach subsequent items

I think this may help

ClassMethod CleanNull(json As %DynamicObject) As %DynamicObject
{
  Set iter = json.%GetIterator()
  Set toRemove = ""
  While iter.%GetNext(.key, .value) {
    Set type = json.%GetTypeOf(key)
    If (type="null") {
      Set toRemove = toRemove _ $Listbuild(key)
    }
    ElseIf (type="object")||(type="array") {
      Set $Property(json, key) = ..CleanNull(value)
    }
  }
  Set ptr = 0, corr = 0
  While $Listnext(toRemove, ptr, key) {
    Do json.%Remove(key - corr)
    set corr = corr + 1
  }
  Return json
}

And Testing metho

ClassMethod TestJSON()
{
  set json = {
    "recipients": [ 
      { "name":"Utsavi", "email":"utsavi@gmail.com"},
      { "name":"Utsavi 1", "email":"utsavi1@gmail.com"},
      null, null
    ],
    "content":[null, {"title":"Test.pdf", "data":"ygwehfbnwfbhew"} ]
  }
  Set result = ..CleanNull(json)
  Do result.%ToJSON()
}

Will return this

{"recipients":[{"name":"Utsavi","email":"utsavi@gmail.com"},{"name":"Utsavi 1","email":"utsavi1@gmail.com"}],"content":[{"title":"Test.pdf","data":"ygwehfbnwfbhew"}]}

What the issue you faced?

Class User.Rest Extends %CSP.REST
{

XData UrlMap [ XMLNamespace = "http://www.intersystems.com/urlmap" ]
{
<Routes>
<Route Url="/:resource/(.*)" Method="GET" Call="GetResource" Cors="true"/>
<Route Url="/ping" Method="GET" Call="Ping" Cors="true"/>
</Routes>
}

ClassMethod Ping() As %String
{
  Write {"pong": true}.%ToJSON()
  Return $$$OK
}

ClassMethod GetResource(pResource As %String, pId As %String) As %Status
{
  Write {"resource": (pResource), "id": (pId)}.%ToJSON()
  Return $$$OK
}

}

With this REST class, I can do queries like this http://localhost:52773/rest/patient/test/123/456, with no issues it returns {"resource":"patient","id":"test/123/456"}
