Error loading workspace - SR.net_http_client_execution_error

[Richard Lee]

Hello,

I cloned the barcode scanner sample app in the in-browser client and I can open it without any problems.

I also tried to open it in Windows client. I got the "Error loading workspace" message. Detail message is "Error occurred while loading workspace 'Barcode Scanner App'; SR.net_http_client_execution_error.

Any help would be much appreciated,

Regards,

Richard

Hello Richard,

This is a really weird error as the Windows and In-browser client share the same workspace. If restarting the Windows client did not help and the problem persists, we would appreciate if you provide us with session logs from FiddlerCap (with the Decrypt HTTPS Traffic option enabled). Start it prior AppBuilder Windows client and save the HTTP requests to disk. Zip the sessions and upload the file to a free file share server and give us the link here.

Regards,

Hello Steve,

I found the issue was in our proxy server. I can open the project in Windows client.

Thanks for your help.
