Hieu Bui (Customer) asked a question.
I've setup .net core project but this issue appear, after I reload the new data or widget still show but it's very inconvenience
Progress.Sitefinity.RestSdk.Exceptions.ErrorCodeException: The request failed with status code 404 (Not Found).
I also update web service and web config file
<add key="sf:enableRendererFeatures14" value="true" />
<add key="sf:enableRendererDiagnostics" value="true" />
You don't need the sf:enableRendererFeatures14 in the web config but that isn't an issue per say. Are you hosting the CMS in IIS? Then running the renderer through Visual Studio or dotnet run. If you have the CMS in IIS then you need to ensure you have the Progress.Sitefinity.Cloud.AppGatewayHostRewriteModule.
