Hi, in my Angular 13 Projet I add the ReportViewer. Work well with the "online" Telerik REST service like with the CLI provided demo.

But on my .Net Core Rest service I got a 404 not found on :

https://localhost:44379/reports/clients/e99adeb6a60/parameters

If I use the clientId received by the viewer and try the same POST in Postman, I got no error and the response got Parameters [] (I test with Barcodes report that do not have anay parameters.

Why the viewer got a 404 Not found in the network tab?

In the viewer the error is:

Unable to get report parameters.
Report 'Barcodes%20Report.trbp' cannot be resolved.

EDIT:

Testing directly in the CLI Telerik Demo and I got the same error. Using the Telerik Demo and online REST Telerik service:

<tr-viewer #viewer1 
    [containerStyle]="viewerContainerStyle"
    [serviceUrl]="'https://demos.telerik.com/reporting/api/reports/'"
    [reportSource]="{
        report: 'Barcodes Report.trbp',
        parameters: {}
    }"
    [viewMode]="'INTERACTIVE'"
    [scaleMode]="'SPECIFIC'"
    [scale]="1.0"
    [ready]="ready"
    [viewerToolTipOpening]="viewerToolTipOpening"
    [enableAccessibility]="false">
</tr-viewer>

Error loading the report viewer's templates. (templateUrl = 'domain-name/api/reports/resources/templates/telerikReportViewerTemplate-15.2.21.915.html/').

Facing this issue , application is in angular and .net

Hi,

Web Service Data Source has parameters as you can see from the picture below. We can define design-time value for the parameters. The design-time values help us during designing our report (for example, we can see selected properties from standalone & web report designer). In our case, we also need to modify some report programmatically, we need to create new web service data source or update existed one. 

  The question is how to set design-time value for a parameter of web service data source programmatically? 

Hi,

We have upgraded our Telerik reporting version to 15.1.21.616 and we are using the Upgrade Wizard to update all the telerik assemblies in the project. When we called /api/reports/formats, below error occurs:

"ExceptionMessage": "Multiple actions were found that match the request:  Formats on type WebApi.Controllers.ReportsController GetClientsSessionTimeoutSeconds on type WebApi.Controllers.ReportsController", "ExceptionType": "System.InvalidOperationException",
"StackTrace": "   at System.Web.Http.Controllers.ApiControllerActionSelector.ActionSelectorCacheItem.SelectAction(HttpControllerContext controllerContext)\r\n   at System.Web.Http.Controllers.ApiControllerActionSelector.SelectAction(HttpControllerContext controllerContext)\r\n   at System.Web.Http.ApiController.ExecuteAsync(HttpControllerContext controllerContext, CancellationToken cancellationToken)\r\n   at System.Web.Http.Dispatcher.HttpControllerDispatcher.<SendAsync>d__15.MoveNext()"

Once we downgrade back to 15.0.21.224, the error gone.

Please help. Thank you.
