You are sharing a map image layer that is configured with a WFS layer, WMS layer, or WCS capability. One or more of the service properties of these additional layers or capabilities contains reserved characters.
Replace reserved characters with the appropriate escape sequence.
Hover over the analyzer message. Click the Options button that appears and click Apply escape sequence to reserved characters. Reserved characters are automatically replaced with the escape sequences shown in the table below.
Open Geospatial Consortium (OGC) services—such as WMS, WFS, and WCS—should not include reserved characters in their service properties. Reserved characters may cause problems with some client applications. It is recommended that you remove reserved characters from service properties or replace them with the appropriate escape sequence.
