Trouble selecting on a date field

[JosephElfelt1]

I am working with a MapServer layer that support dynamic layers.  The data is tornado damage going back a number of years.  My goal is to select only 2019 data.

This tile call displays all the data:

https://services.dat.noaa.gov/arcgis/rest/services/nws_damageassessmenttoolkit/DamageViewer/MapServe... 

In order to select 2019 data I add the following dynamicLayers parameter with a definition expression:

&dynamicLayers=[{"source":{"type":"mapLayer","mapLayerId":0},"definitionExpression":"stormdate > DATE '2019-01-01'"}]

Here is the tile call with the dynamicLayers parameter added.  This call displays...nothing.

https://services.dat.noaa.gov/arcgis/rest/services/nws_damageassessmenttoolkit/DamageViewer/MapServer/export?bbox=-11767633.378559455,5058296.783799826,-9001224.450862357,3957603.5764932865&size=1131,450&dpi=96&format=png24&transparent=true&bboxSR=3857&imageSR=3857&layers=show:0&f=image&dynamicLayers=[{"source":{"type":"mapLayer","mapLayerId":0},"definitionExpression":"stormdate > DATE '2019-01-01'"}]

Where did I mess up?

Note that I do not want to change how the data is rendered.  Instead I simply want to display a subset of the data.

Since you are making a URL request, it needs to be URL encoded.  You might try:

https://services.dat.noaa.gov/arcgis/rest/services/nws_damageassessmenttoolkit/DamageViewer/MapServe...

See: HTML URL Encoding Reference  and urlencoder.org

Thanks but that does not solve my problem.

Adding url encoding does not let me select just the 2019 data.
