ReportViewer failed to load image from database.

[Hafiz]

I'm using BoldReport.ASpNet.Core 2.3.39 with Asp Net Core 3.1.8.

I've followed step in documentation to create Report Viewer with ASP Net Core.

However, when I preview RDL report with image from database, image url is showing below message.

{"type":"https://tools.ietf.org/html/rfc7231#section-6.5.13","title":"Unsupported Media Type","status":415,"traceId":"|7360524d-42ced83217cd6b4a."}

image url:http://localhost:51286/api/Report/GetResource/?key=d1178e17-2eb3-4da3-8a83-7e475149735c_sf_ImageQR_76a29788-ca14-4c85-bb27-b5dfaaffe297&resourcetype=sfimg&isPrint=false

I've tried to debug GetResource function in Report api controller but it never get called.

//Get action for getting resources from the report

[ActionName("GetResource")]

[AcceptVerbs("GET")]

// Method will be called from Report Viewer client to get the image src for Image report item.

public object GetResource(ReportResource resource)

{

   return ReportHelper.GetResource(resource, this, _cache);

}

After spending few hours I finally get it to work by adding '[FromQuery]'

public object GetResource([FromQuery]ReportResource resource)

{

    return ReportHelper.GetResource(resource, this, _cache);

}

Hope anyone can confirm this and fix the ReportViewer ASP Net Core documentation.

Hi RWEM, 

The mentioned issue occurs when using the APIController attribute in controller class file. So could you please remove the APIController as shown in below help documentation to avoiding the mentioned problem at your end.
