Problem getting GIS ESRI Integration functional

[jim_metcalf]

Here is what we are using.
-OnBase Version 16.0.0.40  
-GIS Integration using webapi javascript (not silverlight)
- WebApp builder from Esri 1.3

Attached is a screenshot of the configuration setting we are having problems with.

We have installed the GIS Service and a map is now displaying from the onbase server.... "map.aspx" 

we are not fully functional yet and are stuck in a configuration setup piece that is failing.  When we are configuring the widget from the GIS server, it asks us for a service url.  Yhe service url we supply the interface fires off an error that says.  

"Error. The service url maybe incorrect or misconfigured!"

Can someone help key me in on what the problem maybe?  We have been stuck for a few weeks on this and decided to give the community support.
Attached is a screenshot of the GIS Interface that is prompting for the Service URL.

"ENTER A VALID GIS ONBASE URL" is the prompt we are filling out on this process.  

Please help

Thank You!

Hi Jeff,

Thanks for reaching out on Community! Sorry for the delay in response. The error you are seeing dose not necessarily mean the GIS Service URL you are using is incorrect. You have a few options of how to deal with this.

The error can sometimes be thrown due to CORS issues. You can edit the CORS settings in the GIS Web API web.config file, as well as the CORS web.config file in order to enable CORS. This sometimes takes care of the error you are seeing.

However, another step is to proceed despite the error and download the application so you can test it in its deployed nature. The GIS Service URL can be altered one the application is downloaded. The integration is not supported in a 'hosted mode', and to fully test the features, it must be downloaded and deployed.

I hope this helps.
