The Pipeline Parameter Referenced by the Task Does Not Exist

Background

Pipeline parameters can be transferred to each task using the ${parameter name} format. If a parameter associated by using ${parameter name} is not on the pipeline parameter list, a message is displayed, indicating that the parameter is not specified.

Symptom

After you edit a pipeline and click Save, a message indicates that a pipeline parameter referenced by the task does not exist.

Root Cause

1. Click the name of the task for which the error is reported. On the task orchestration page, view the task parameter settings.

   

2. Access and view Parameter Configuration page.

   The releaseversion parameter referenced by the task parameter is not configured on the pipeline parameter list. As a result, this exception is reported.

   

Solution

Use either of the following methods to add a referenced parameter (for example, releaseversion) to the pipeline parameter list:

• On the Parameter Configuration page of the pipeline, click Create now to add a parameter.
• Click the name of the failed task. On the task orchestration page, hover over releaseversion, and click Set as Pipeline Parameter to add a parameter.
