Last update: Mon Feb 24 2025 00:00:00 GMT+0000 (Coordinated Universal Time)

During a production pipeline in Adobe Experience Manager (AEM) as a Cloud Service, the pipeline fails to progress beyond the  Deployment phase due to service user name conflicts with existing user group names in RepoInit scripts. This article provides steps to resolve these conflicts.

Description description

Environment

  • Adobe Experience Manager (AEM) as a Cloud Service - Sites
  • Component: Cloud Manager

Issue/Symptoms

During the execution of a production pipeline in AEM as a Cloud Service, the pipeline completes up to the Build Images  stage but fails during the Deployment  phase at the Install mutable content  step.

The symptoms include:

  • Prolonged execution time before failure with previous instances taking several hours.

  • The deployment process becomes stuck.

  • The following errors appear in the error logs:

Cause

The root cause identified for this issue is a conflict with existing user or group names within the repository. In particular, if there is an attempt to create a service user with an ID that matches an existing group name, it results in conflicts that prevent successful deployment.

Resolution resolution

To resolve conflicts when creating service users during deployment, follow these steps:

  1. Verify if any existing groups or users have the same names as those being created by your RepoInit script.
  2. Ensure that service user names specified in your RepoInit script do not conflict with any pre-existing user or group IDs within your environment.
    • Example adjustment might involve renaming either the conflicting group/user or altering your script’s naming conventions.
  3. Once changes are made to avoid naming conflicts, redeploy your code through the pipeline and verify whether it proceeds previously failing steps.
  4. Test deployments on non-production environments first after making adjustments to ensure no further issues occur before attempting another production deployment.
  5. If further assistance is required, consider reaching out for additional support from Adobe’s technical team.
