Print Widget not working for layers that require a proxy url

Question

Using the Viewer for Flex Application builder 3.1, I've added a couple of operational layers that require a proxy.  These display fine, but the print widget generates an error.  When using the print widget, the "Web Map as JSON" that is generated does not include the proxy url before these operational layers. The Viewer reports:  "RPC fault, failed to create layer from service at....".  When I test at the REST endpoint, I can take the JSON generated by the print widget and just add the proxy url before service url and everything works splendidly.
  
Is this a bug with the Application builder, or am I missing some configuration option for the print widget to tell it to use the proxy?  I see some other widgets that have a proxy checkbox, but don't see that with the print widget.

Thanks in advance,
Sebastian Roberts

Saurabh,

I just had a similar issue with the same print service when using it in the Web AppBuilder print widget. In resolving that issue, it reminded me how I resolved it with the Flex Print widget.  Using https in the url for the print service resolves the issue for my services.  Also be sure to include an https path in the config file of your dynamic proxy page if you are using one.

Hello Sebastian,

Thanks again for your response!!

Just a last query on this one , i cannot see the complete Web_Map_as_JSON string in your reply. Can you please check for me whether in your case string contains token or not. Jim from this post is suggesting this so just wanna crosscheck.Secured Printing Service  Thanks Again

Hello Saurabh,

We are using our own public print service (our own toolbox if you will), and calling it using https.

https: //countyserver/arcgis/rest/services/public/CountyPrintService/GPServer/Export%20Web%20Map/submitJob

The webmap as json in the print request is pasted below.  You can see we are using some internal services which are protected and require a proxy.  I don't see any significant configuration in the print service

Regards,

Sebastian
