Are there any data types that the dissolve tool won't accept as a field to aggregate by? I am getting this error but I think it's a error of misdirection because my python tool works perfectly fine when run locally but after it is published to ArcGIS Server, I get this error when it reaches the line in the script where it runs the dissolve tool. I am trying to dissolve using numerous fields with data types of string, integer, float, GUID, and date. I'm not understanding why it would work in ArcMap but not when it's published to the server.
Yup, that was the problem. I got around it by copying the GUID field to a field of string data type, doing the dissolve, and copying the string data back to a GUID field and carrying on with the script. I understand GUIDs are supposed to be unique so there shouldn't be a need to dissolve them, but that's not so in my case. It annoys me that it works fine in ArcMap and then when published to Server it breaks, making debugging a painfully slow process.
