It looks like you're enabled Network Inspect, so it will use XHR from WebWorker, it's different from the XHR implementation of RN, so we have to pay attention to some limitations.

You need to track what requests use these headers.

yup, seems it's from my project configuration
upgrade it to react native 0.45/reinit the project then the error is gone

I need to set User-Agent and Cookie, which are unsafe.
Tried it on a fresh React Native 0.45.1 project, got "Refused to set unsafe header" error anyway.

According to the XMLHttpRequest standard (see step 5 here) there are "forbidden" headers which cannot be set. There's no way around it (other than patching the browser).
