error submitting GP job

Town_ofSnowflake

I've built a web application that uses a GP service to extracts data (using a modification of the Clip and Slip) using the ArcGIS for Javascript API.  The GP service works via URL and within ArcGIS Desktop.  When I try to submit a job through the application, a single GET request is made to my server and I get the error: "Error submitting job..... code 500."  I'm using HTTPFox to watch the traffic between browser/server.  Note: I'm submitting the required parameters and I believe I am referencing the correct URL to the GP service  "<servername>/ArcGIS/rest/services/GPServer/<toolname>"

Thanks for the response.

This problem was solved using URL debugging / HTTPFox

I submitted the job through "<servername>/ArcGIS/rest/services/GPServer/<toolname>/submitJob" and compared the URL string to the one being sent directly from within the application.

I had an optional parameters in the GP tool that I was not declaring in the parameters sent to the job from within the application. However, the job sent from "<servername>/ArcGIS/rest/services/GPServer/<toolname>/submitJob" included the optional parameter in the string that was sent to the GIS server.

I solved the issue by including the optional parameter in the parameter list with empty quotes: var params = {optionalParameter = ""....}
