A line feature class shared from ArcGIS Pro does not display in ArcGIS Online

Description

When publishing a line feature class as a hosted feature layer from ArcGIS Pro to ArcGIS Online, the line feature class fails to display, as shown in the image below.

Cause

When m-values and z-values are enabled for a line feature class, the line features overlap and do not appear when published in ArcGIS Online.

Solution or Workaround

Disable m-values and z-values for the output layer in the Environment Settings prior to publishing.

1. In ArcGIS Pro, right-click the line feature class, and click Properties. Ensure the feature class has m-values or z-values enabled, and click Cancel.
   
   

• In the Geoprocessing pane, open the Feature Class to Feature Class tool.
• Set the output name and location in the Parameters tab.
  
  

• Click Environments > Output has M Values > Disabled > Output has Z Values > Disabled.
  
  

• Click Run. A new feature class is created.
• Publish the new feature class to ArcGIS Online. The lines are displayed in ArcGIS Online map viewer.
