PROBLEM:
The PR enhances to address the issue "TypeError:cannot read properties of undefined (readingisProjectRoot)
identified the root cause of the issue and implemented the solution. The changes inreify.js handle cases whereisProjectRoot is undefined.The code assumes all nodes in the dependency tree have theisProjectRoot property. However, in some cases(e.g, when a dependency is missing or improperly linked) the node object is undefined, leading to the error.

Solution:

• Added a null/undefined check before accessing theisProjectRoot property.
• Updated the logic inreify.js to ensure that the code gracefully handles cases where the node object is undefined.
