Problem with JSON file datasource

[SIEN]

Hi, I'm developing a report with standalone designer (version 18.2.24.824) with a JSON Data Source. When I put my JSON inline, no problem. But when I follow this instructions, I have no data (I bind my data source on a table). No errors, but no data.

The content of the JSON file :

{"eleves":[{"numero":1,"nom":"Toto","prenom":"Toto "},{"numero":2,"nom":"Tata","prenom":"Tata "},{"numero":3,"nom":"Tutu","prenom":"Tutu "}]}

 

On my data source, I set the property "Data Selector" as "eleves".

I create a report parameter named "DataSourceFileName".

I run the report (from an ASP.NET Core app) with the follwing value for the parameter : @"c:\\temp\\Telerik report\\Data\\data.json"

My Table in the report has following parameters :

• DataSource : ListeElevesDataSource [Telerik.Reporting.JsonDataSource]
• Telerik.Reporting.Binding : 
•     Path : DataSource.Source
•     Expression : GetUri(Parameters.DataSourceFileName.Value, "Absolute")

 

Any advice ? Thank you

I answer myself. The expression to use is " = Uri(Parameters.DataSourceFileName.Value, "absolute")"

The function is Uri() and not GetUri().

It will be good to correct the page I mention in my question.
