Steps To Reproduce

Create API with AWS Lambda and API Gateway
Call the following code:

var headers = {
   'Authorization': 'Bearer ${Cognito.signInUserSession.idToken.jwtToken}'
 }
 console.log("Headers" , headers);
 const qs = `{users(username: "aUserName") {username, leagues {name, start, currentTime, ready, creator, totalPlayers, joinedPlayers, creatorInfo {fullName}, draftPicks{user{username, fullName} order,numTickets}}} }`

 const URL = 'https://someID.execute-api.us-east-1.amazonaws.com/Prod/graphql?query=${qs}';
 return (
   fetch(URL, {
     method: 'GET',
     headers,
   })

Use IOS and Postman, it works fine, on Android I get status 400

I’m getting the same error on RN version 0.61.5 (latest). The exact same call with the same params works on iOS (both device and simulator) and Postman on the web but fails on anything Android (device, emulators with different OS versions). It’s an HTTPS call. It’s also interesting that it works when RN debugger is enabled.

@hramos I can confirm that this is an issue on the latest RN release as well.
