I have a geoprocessing service that has several fields, most of them are strings.
One field in particular is the streamcode, which can be up to 35 characters (numbers as characters).
When I run the script in ArcCatalog, it works, even with a long value in the streamcode field.
Then I publish it.
When I run the same job with the same parameters from the rest service GPServer, it does not work. The problem is the streamcode field can only have 19 characters.
I have not found any way to specify the number of characters and I find it weird that this one field can't handle anything more than 19.
