The Angular application is not functioning properly after running npm start, even though all the necessary packages have

Encountering a perplexing issue with my Angular application. After checking out the code on my new machine, I attempted to run my existing Angular 12 project. However, despite the application running properly in the command prompt, it is not functioning as expected and displaying the following error screen:

After successfully installing the app using npm install, I noticed several deprecated warnings like:

Following the installation, when trying to launch the app using npm start, I encountered another peculiar situation where the app runs correctly in the command prompt but fails to load in the browser, resulting in a blank page with console errors:

The versions of Angular being used are specified in the screenshots below:

If anyone can offer assistance with resolving this issue, I would greatly appreciate it. I have been struggling to find a solution on my own.

Thank you.

Answer №1

If you take a look at the error message, it reads:

[ERROR ->]

That is where the problem lies. Make sure to properly escape all {} symbols.

Replace this:

X-API-KEY: <span>{{</span>@Cmd | Step-2-content <span>}}</span>

With this:

X-API-KEY: <span>{{ '{{' }}</span>@Cmd | Step-2-content <span>{{ '}}' }}</span>

There might be other instances of this issue, but the principle remains the same.
