PROBLEM:
The PR enhances to address the issue "TypeError:cannot read properties of undefined (reading isProjectRoot)
identified the root cause of the issue and implemented the solution. The changes in reify.js handle cases where isProjectRoot is undefined.The code assumes all nodes in the dependency tree have the isProjectRoot 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 the isProjectRoot property.
• Updated the logic in reify.js to ensure that the code gracefully handles cases where the node object is undefined.
