wix-fetch post behavior changed

Hello,

I have a site that utilizes the wix-fetch module to make HTTP POST calls. Up until a few days ago, I was able to perform POSTs like so and everything worked:

import { fetch } from 'wix-fetch';
fetch("https://some-url", {
    method: "POST",
    body: JSON.stringify({
        data: "some data"
    }),
});

However, then a few days ago my site stopped working. I discovered that the fetch call was no longer sending the request body. I was very confused by this and could find no documentation explaining that anything changed. After trial and error, I discovered that I had to add the “Content-Type” header to make it work as before:

import { fetch } from 'wix-fetch';
fetch("https://some-url", {
    method: "POST",
    headers: {
        "Content-Type": "application/json"
    },
    body: JSON.stringify({
        data: "some data"
    }),
});

Was this an intentional change? Is there any way I can be informed in the future of changes like this so my site doesn’t just break next time? I have customers whose product sales were likely impacted because of the outage this caused.

Thanks,
Andrew
