Running analysis tools on feature layers or hosted feature layers in ArcGIS Online Map Viewer Classic loads indefinitely

Description

Running analysis tools on feature layers or hosted feature layers in ArcGIS Online Map Viewer Classic loads indefinitely and in some cases, an invalid output is created.

Cause

• The spatial index of the hosted feature layer is not properly rebuilt when published to ArcGIS Online.
• Feature layers created using a CSV or TXT file are incorrectly formatted. Refer to ArcGIS Online: CSV and TXT files for information on formatting CSV or TXT files before adding the files as layers in Map Viewer Classic.
• The analysis cannot be completed due to insufficient credits to run analysis tools. Refer to ArcGIS Online: Understand credits for more information.

Solution or Workaround

Use one of the following workarounds to resolve the issue.

Repair the spatial index of the layers

1. In ArcGIS Online, navigate to the Content tab.
2. Click the hosted feature layer to open the hosted feature layer's item page.
3. On the Settings tab, check the Enable Editing option.

4. Click Rebuild Indexes under the Manage Spatial Indexes section.

5. Check the feature layers checkboxes to rebuild spatial indexes for the layers, and click Rebuild.

Publish the feature layers as a hosted feature layer

If the feature layer is used to run an analysis, an alternative is to publish the feature layer as a hosted feature layer before running the analysis tools on the layers in Map Viewer Classic. Refer to ArcGIS Online: Publish hosted feature layers for steps and more information.
