Attempting to retrieve a URL using Angular/Typescript is generating an Unknown Error instead of the expected successful response

Question

Attempting to retrieve a URL using Angular/Typescript is generating an Unknown Error instead of the expected successful response

I'm trying to make a simple HTTP function call through TypeScript (Angular) to an API hosted as a function in Azure.

When I call the URL through Postman or directly in the browser, everything works perfectly.

However, when I try to call the URL using http.get like this:

this.http.get<any>(myUrl)
    .subscribe({
    next: data => {
        console.log(data);
    },
    error: error => {            
        console.error('There was an error!', error);
    }});

I always end up in the error part with an "Unknown Error."

Strangely, when I check the browser's (Chrome) network tools, the request was successfully sent with a 200 status code and the response contains exactly what I expected.

So, why is the error part of the code being triggered instead of the success part?

I successfully managed to fix the issue without any external help. The issue stemmed from the fact that the API did not return JSON data, but rather plain text. In order to handle this, I explicitly had to define the responseType as 'text':

this.http.get<any>(myUrl, {responseType: 'text'})
   .subscribe({
      next: data => {
         console.log(data);
      },
      error: error => {            
         console.error('Encountered an error!', error);
      }});
