00326: The style does not contain a valid <value> symbol
The style you are sharing doesn't contain any style items or contains one or more invalid style items with respect to the style.
The <value> parameter refers to the symbol type: 2D, 3D model marker, or dictionary.
Only point, line, polygon, and text symbols, colors, and color schemes are supported style items for 2D styles. Colors and color schemes are supported only when sharing to ArcGIS Online or ArcGIS Enterprise 12.1 and later.
3D model marker web styles must contain only point symbols with only 3D model marker symbol layers.
Symbols in dictionary styles comprise different components to create complete symbols. Ensure that the dictionary style file (.stylx) contains a meta table that stores both the dictionary configuration file and the dictionary script. See Understanding the dictionary for more information. Only point, line, polygon, and text symbols are supported style items for dictionary styles.
