Error: "Unresolved function or method present()" when using LoadingController

Hi,
When I use the LoadingController in my project, I see the following error: "Unresolved function or method present()"

Here is the screenshot code that I have in my file:

As we can see from the screenshot, there are 2 pieces of code that show the same error. The code from lines: 51-61 are a direct copy of the code from the ionic documentation that can be seen under Usage

The code from lines: 63-69 are the trimmed down and basic version of the code and for testing purposes await is removed in front of the loading.present();. Yet it throws the same error as the original code above. What can we do to fix the issue so that Intellij Idea (IDE) stops complaining about the same?

Following is the info from my package.json:

which ionic version?

Does that answer your question?

I try this example in my ionic 4 project. It’s working fine.

Functionality wise, it seems to be working. But even then Intellij Idea is reporting the Typescript error. LoadingController does not seem to have method present() and that is why Typescript is reporting the error via TSLint.

This causes additional issues whenever I try to push my files using Git, as the IDE complains that there errors in the code and hence it stops my Git push to my Git repository. Then I have to manually inspect each and every error and then push the code, even though it still complains about those errors (because they are not resolved).

Does that make sense?
