Opening PDF from API response to new tab in Angular

I could really use some help here, I have spent nearly three days on this.

Within my Node application I have an API call that uses https call to an external API to return a PDF which looks like the below code. (I understand I could call the external API from the frontend Angular code, however corporate rules prevent me from doing so)

-Node

var options = {
host: config.fake.host,
path: config.fake.apiUrl + pdfId,
method: 'GET',
rejectUnauthorized: false,
headers: config.fake.headers
};
console.log(options);
api.getCall(options, function (status, response) {
res.status(status).send(response);
});


Node then returns the PDF (in plain/text), which I am able to view the pdf data with the Chrome devtools. This is where im getting lost. I am trying convert the pdf data into a blob and then open the pdf in a new tab but when the new tab opens I get a dialog saying "Failed to load PDF document." The Angular code works if I hardcode a test pdf file and return it to the frontend, it does exactly what I need it too.

this._http.get(url, {responseType: 'blob'}).subscribe( data => {
console.log(data);
var file = new Blob([data], {type: 'application/pdf'});
var fileURL = URL.createObjectURL(file);
window.open(fileURL);
});


Unfortunately, I have exhausted all the google resources I could find and have tried alot more than just the above. I'd appreciate any input I could get on this. Thanks!
