Typescript struggles to comprehend the nullish-coalescing operator

Within my Vue + TypeScript application, I've incorporated an external package called @moj/pagination-layout. This package utilizes the nullish operator internally. However, when attempting to run the build process, it encounters a failure and presents the following error:

 ERROR  Failed to compile with 1 error                                                                                                                                                                1:10:16 PM

This issue typically arises when your module has not been transpiled by babel.

To resolve this, navigate to your vue.config.js file and configure the transpileDependencies option. Simply add the name of the module you wish to transpile, along with its dependencies, in an array format. Once done, everything should start working seamlessly.

Here is a sample configuration:

module.exports = {
    transpileDependencies: ['bootstrap-vue']
}
