Code generation error when creating master/detail template page

Radzen Studio Blazor Server
1

I have some simple REST JSON data like this:

[  
   {
      "articleCode":208,
      "articleName":"Milk",
      "todaysCount":100,
      "totalCount":155,
      "olderCount":55,
      "todaysVolume":1000,
      "totalVolume":1550,
      "olderVolume":550,
      "lanes": 
         [
            {
               "laneId":1,
               "closed":false,
               "maintenance":true,
               "todaysCount":100,
               "totalCount":100,
               "olderCount":0,
               "todaysVolume":1000,
               "totalVolume":1000,
               "olderVolume":0
            },
            {
               "laneId":4,
               "closed":false,
               "maintenance":true,
               "todaysCount":0,
               "totalCount":55,
               "olderCount":55,
               "todaysVolume":0,
               "totalVolume":550,
               "olderVolume":0
            }            
         ]
   },
   {
      "articleCode":210,
      "articleName":"Honey",
      "todaysCount":200,
      "totalCount":0,
      "olderCount":0,
      "todaysVolume":2000,
      "totalVolume":0,
      "olderVolume":0,
      "lanes": 
         [
            {
               "laneId":5,
               "closed":false,
               "maintenance":true,
               "todaysCount":50,
               "totalCount":0,
               "olderCount":0,
               "todaysVolume":500,
               "totalVolume":500,
               "olderVolume":0
            },
            {
               "laneId":6,
               "closed":false,
               "maintenance":true,
               "todaysCount":150,
               "totalCount":0,
               "olderCount":0,
               "todaysVolume":1500,
               "totalVolume":0,
               "olderVolume":0
            }            
         ]
   }
]

I have defined my dataset like this in Radzen (all the data source methods work fine):

I want to display this data in a master / detail fashion. I try to create a master/detail template page like this;

When i try to save / create the template page, i get this error:

Why do i get this code generation error?

Hi,

Unfortunately we are not sure what's causing the error. Is just with master/detail templates or you get the same with CRUD pages template? If you are Radzen subscriber you can send us your app at info@radzen.com to debug it.

Hi

I do get the same error when i select the CRUD pages template.
I'm not a subscriber.

I will try to recreate everything from scratch to see if that helps. If not, maybe i should try to downgrade some versions? Can this be a bug that has been introduced lately?

4

Sounds more like unsupported REST schema - downgrading most probably will not help much.

5

If you look at how the raw data looks, and how i have defined it in the IDE, have i defined everything correctly? Or are you saying that this is a format that is not supported by Radzen?

By the way this is the console output when the code generation fails:

Yes, this is what I'm referring to however our support, debugging, etc. is available for paid customers only.

Absolutely understand your point on 1-1 support.

However this seems to be a bug that is easily replicated:

  1. Create a new REST data source defined like this:
    image
    image

  2. Create a template page (master/detail).
    Code generation will fail.

Attached is my meta data JSON file for the datasource:
