ESRI ArcGIS REST API URL giving me a blank image

I'm trying to use the following URL to export a map image and I'm not getting anything other than a blank image...

http://demographics6.arcgis.com/arcgis/rest/services/USA_Demographics_and_Boundaries_2016/MapServer/export?f=json&format=png&bbox=-82.728110%2C27.719379%2C-82.532320%2C27.816795&size=600,600&token=[my-token]

Any ideas?

Solution

Are you constructing this url yourself or is that request coming from a layer added to the map?

After logging in to ArcGIS Online, I was able to use the export endpoint just fine with this url:

http://demographics6.arcgis.com/arcgis/rest/services/USA_Demographics_and_Boundaries_2016/MapServer/export?bbox=-2.601910765504469E7%2C4619421.289780159%2C1199812.3691861853%2C1.6262309438175105E7&size=600%2C600&format=png&f=json

My hunch is you are supplying an invalid bounding box, it looks like it may be in a different spatial reference than the service, the service is expecting web mercator (102100) and looks like you may be giving it geographic (4326)
