After posting data to the navigation, I retrieve it and then use the following code:
.then(data => console.log(data.PathPDF))
.then(data => window.open(data.PathPDF, '_blank', 'noopener,noreferrer'));
While I can successfully retrieve the value in the console with the first line of code, the window.open function generates an error stating "Cannot read property 'PathPDF' of undefined".
