Using version 9.1.0

I submit a REST GET request with the following where <lab's website> is our hostname:

https://<lab's website>/rest/util/generateGraphicImage?&productName=%5B%22GTG_00_CAT_010_CONUS%22%5D&airportIdentifier=PDX001100&radius=100&minRunwayLength=50&labelsOn=true&width=1000&height=800&renderSectionals=false&forecastHour=15&includeCodedMessages=true&versionRequested=20170327

I get a 400 error code and the following response:

Status:
