Cannot access artifact repositories when creating a task from TAC 7.0.1 and 7.1.1

Problem Description

In TAC, (Settings > Configuration) the Artifact Repository is set up correctly and shows green check marks. However when attempting to create a new artifact task from TAC, and trying to browse the artifact repository, it fails with the following error:



TAC technical log file shows the following error:

java.lang.IllegalArgumentException: json string can not be null or empty
at com.jayway.jsonpath.internal.Utils.notEmpty(
at com.jayway.jsonpath.internal.ParseContextImpl.parse(


Root Cause

In this case, the Artifact Repository is using Nexus version 3.15.2, which requires a patch in TAC 7.0.1 and 7.1.1.



  1. Contact Talend Support to request the patch that applies to your version of TAC:

    • For TAC 7.0.1 users, request:
    • For TAC 7.1.1 users, request:
  2. Use the patch Readme file steps (embedded in the patch zip file) to apply the patch.
