Overview :

When we encounter a failure while importing workflows in AutomationEdge. The system throws an unexpected runtime exception due to the inability to create a temporary directory on the application server.

Error Description :

The logs reveal the following error during the workflow import:

com.automationedge.aeutil.exception.AECustomRuntimeException: Unexpected error occurred. Please contact AutomationEdge Administrator.

Caused by:
java.nio.file.AccessDeniedException:
E:\AutomationEdge\tools\apache-tomcat-9.0.65\temp\AE_ImportWflow_<random_id>

Error Message:
Could not create temp directory

: Root Cause :

The issue occurs when the Tomcat server does not have sufficient permissions to create directories in its configured temporary directory:

E:\AutomationEdge\tools\apache-tomcat-9.0.65\temp

This typically happens when:

• Tomcat is running under a restricted Windows user account (e.g., LocalService/NetworkService)
• Folder permissions do not allow write or modify access
• Security policies or antivirus tools restrict directory creation

Resolution :

Step 1: Grant Required Permissions

1. Navigate to the Tomcat temp directory:

   E:\AutomationEdge\tools\apache-tomcat-9.0.65\temp

2. Right-click → Properties → Security
3. Provide Full Control or Modify, Read,Write permissions to:
   • The user running the Tomcat service
   • Or the Users group (as per organizational policy)

✅ Verification

• Retry workflow import
• Confirm no AccessDeniedException appears in logs.
