Resolve an "Uncaught ReferenceError" by importing an unused component to fix the error of not being able to access a variable before initialization

In my service file, where I store all other services used in the frontend, there is an import section that includes one component even though it is not being used.

import { VacationComponent } from 'app/view/vacation/vacation.component';

When I remove this unused import, I encounter the following error:

main-es2015.0cad4195744251a340b5.js:1 Uncaught ReferenceError: Cannot access 'nX' before initialization

I find it perplexing how removing an unused import can resolve this error, especially since the imported component does not have a variable named "nX" within it. The main file mentioned in the error message contains a definition of nX which looks like the following:

let nX=(()=>{class t{constructor(t,e){this.service=t,this.dialog=e,this.isChecked=!1}

I cannot see any connection to the imported Component file in this context.

Answer №1

It seems like the error message is pointing to multiple files, making it difficult to identify which one is causing the issue.

The main file mentioned in the error message contains a definition of nX.

However, it raises the question - has nX been defined before being used?

One way to potentially resolve this issue with the nX variable is by importing an unused component, which would define the variable in the global scope on its own.

For instance, if this unused import includes window.nX = "bla";, then the variable should no longer be undefined.

Providing the content of the file where the error occurred along with the line number would be beneficial for further investigation. Based on the information provided, it appears that there might be an attempt to use the nX variable before actually defining it within the file.

Answer №2

Everything is back to normal now. It turns out the issue wasn't with the VacationComponent that was imported, but rather with a different component referenced in the Main file. I'm not entirely sure why initially importing the VacationComponent seemed to resolve the problem, but it's working fine now even without it after addressing the underlying issue in the other component.
