Error: Connection InterfaceProviderSpec prevented service: content_renderer from binding interface FILE_ERROR_ACCESS_DENIED

[Olwen Davies]

I am implementing headless chrome as a newbie user.  Following the https://developers.google.com/web/updates/2017/04/headless-chrome

section Taking screenshots. 

The command line and error is below (chl being alias for chrome executable) 

$ chl --headless --disable-gpu --screenshot https://www.chromestatus.com

[1212/160621.547:ERROR:service_manager.cc(157)] Connection InterfaceProviderSpec prevented service: content_renderer from binding interface: blink::mojom::ReportingServiceProxy exposed by: content_browser

[1212/160622.089:ERROR:headless_shell.cc(530)] Writing to file screenshot.png was unsuccessful, could not open file: FILE_ERROR_ACCESS_DENIED

Is there extra set up I need to do to permission file access? 

How can I debug this and move forward?

Thanks,

Olwen

Apparently full file location with parameter will work e.g.

-screenshot="c:\temp2\screen.png" 

Windows will not allow writing to installation folder
