Angular（8）Http.post（）提供SyntaxError：JSON.parse位置0处JSON中的意外令牌O

Question

When I try post data to my server, I'm getting the error:

SyntaxError: Unexpected token O in JSON at position 0 at JSON.parse...

I am not using JSON.parse() so I assume Angulars Http.post() automatically does this?

When I try console.log(JSON.parse(data)), I'm getting:

SyntaxError: Unexpected token o in JSON at position 1...

When I send the data from Postman - works perfectly fine, no errors and the server receives it.

When I send the data in a fetch() api request - also works perfectly fine, no errors whatsoever.

So, this only occurs when I try use angulars HTTP lib and try to post. Below is an example of some JSON data I send and an example of my http post.

Thanks in advance! This has been driving me crazy!

{"tutorialName":"cvbcvbxcvbxcvbbxcv","sections":[]}

this.http.post("http://127.0.0.1:5000/endpoint", JSON.stringify(this.tutorialForm.value)).subscribe();

Turns out the solution was the response type option on HTTP.post in Angular, it didn't align up with the server ( https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/responseType for types) and defaults to JSON. Thank you to all who answered!
