Unable to load class; unsure of origin for class labeled as 'cached'

Working on an Angular 10 project in visual studio code, I've encountered a strange issue. In the /app/_model/ folder, I have classes 'a', 'b', and 'c'. When running the application in MS Edge, I noticed that only classes 'a' and 'c' are loaded during debugging, while class 'b' seems to be missing. Setting a breakpoint in class 'b' results in an 'unbound breakpoint' error.

Despite this, all changes made to class 'b' in VS Code reflect in the code and can be accessed from components. However, during runtime, attempting to call a method like 'test' inside class 'b' throws the error: TypeError: _a.test is not a function. Additionally, the app appears to be using an older version of class 'b' without any clear source.

It's quite perplexing why these issues are specific to class 'b' and have suddenly surfaced. This particular class had been functioning correctly just a week ago, making the situation even stranger.

Any insights or suggestions?

Answer №1

Upon investigation, I have discovered the root cause of the issue. The data is being received via .NET5 WebApi in JSON format. It appears that the classes 'a' and 'c', which I believed were functioning correctly, are actually serializing some properties that should not be included in the JSON response. Although the properties in class 'b' are not being serialized (which is what we want), this also means that the class itself is not being instantiated. To resolve this, I needed to manually initialize the class with the incoming JSON object, similar to the solution discussed here
