Get 500 error with json format getting layers

Discussion created by bridgji on May 24, 2012
When I call http://fmtvmarcgis10/ArcGIS/rest/services/DemoMap2/MapServer/layers?f=json against a map we have containing a geoprocessign service I wrote.
I get {"currentVersion":10.03,"error":{"code":500,"message":"An unexpected error occurred processing the request.","details":[]}}],"tables":[]}
If I chagne it to html format I'm getting the information i expect, I've pasted a sample at the end of the email.

The map this is occuring with has a geoprocessing service I've published  based on the sample in help which seems to publish fine and run as I expect in map.

I'm not sure why formating it as json vs html would cause it to fail.

I don't seem to see anything in the logs.
