Question:

Warning Accessing non-existent property 'padLevels' of module

The warning message you're encountering indicates that there might be a circular dependency issue in your Node.js application. Circular dependencies occur when two or more modules depend on each other in a circular manner, leading to potential runtime issues.

Here are some steps you can take to address this warning:

Identify Circular Dependencies:

Review your module dependencies and try to identify any circular dependencies.

Circular dependencies can sometimes be challenging to spot, so consider using tools like madge or dependency-cruiser to visualize your module dependencies.

Reorganize Code Structure:

Refactor your code to eliminate circular dependencies. This may involve reorganizing the structure of your modules or breaking down larger modules into smaller, more focused ones.

Dependency Injection:

Consider using dependency injection to break the direct dependency between modules. Pass dependencies as parameters to functions or constructors instead of importing them directly.

Delayed Execution:

If possible, delay the execution of code that sets up dependencies until after all modules have been loaded. This might involve moving certain code into functions that are called after the initial module loading.

Use import and require Carefully:

Be consistent in your use of either import or require statements throughout your codebase. Mixing these two can sometimes lead to circular dependency issues.
