Issue/Introduction

This article provides information to customers with very security sensitive environments in which the returned stack traces might be an issue.

Symptoms:
HTTP requests that have hit an error during processing return a stack trace.

Cause

This issue occurs due to the default mode of the H5 client which is to return the stack traces for debug purposes.

Resolution

To resolve this issue, put error.stackTrace.show=false in the webclient.properties.
  1. Navigate to /etc/vmware/vsphere-ui/webclient.properties.
  2. Edit the file webclient.properties.
  3. Go to end of the file and add a line "error.stackTrace.show = false".
  4. Save and Exit the webclient.properties file.
  5. Restart the vsphere-ui service.
Note: This option is available since vSphere 6.5.
