“Troubleshooting Azure Pipelines: Fixing the ‘Cannot Read Properties of Undefined (reading ‘templatePath’)’ Error”

Azure Pipeline Error – Cannot Read Properties of Undefined (Reading ‘templatePath’)
Overview of the Problem
Azure Pipeline is a cloud-based continuous integration and continuous delivery platform that is used to automate the build and deployment of applications. Recently, there have been reports of an error in which users receive the message “Cannot read properties of undefined (reading ‘templatePath’)” when trying to deploy a pipeline. In this blog post, we will explore what this error is, what causes it, and how to resolve it.

What is the Error?
The error that users are receiving is “Cannot read properties of undefined (reading ‘templatePath’)”. This error is caused when the Azure Pipeline runs into an issue while trying to read the templatePath of a pipeline. The templatePath is a parameter used to specify the path of the pipeline template that is being used.

What Causes the Error?
There are several potential causes of this error. The most common cause is due to an incorrect or missing templatePath. If the templatePath is incorrect or missing, then the pipeline will not be able to locate the template and will fail. Additionally, the error can also be caused by a missing or corrupt template file.

How to Resolve the Error?
The first step in resolving the error is to ensure that the templatePath is correct. This can be done by checking the templatePath parameter in the pipeline configuration. If the templatePath is correct, then the next step is to ensure that the template file is present and not corrupt. If the template is found to be missing or corrupt, then it needs to be replaced with a valid template.

Conclusion
The “Cannot read properties of undefined (reading ‘templatePath’)” error can be a frustrating issue to deal with, but it is relatively easy to resolve. The key is to make sure that the templatePath is correct and that the template file is not missing or corrupt. Once this is done, the pipeline should be able to run without issue.
