I have project which needs to authorize client with personal certificate, as react-native cannot do that request I have a bridge module and do that on objective-c, after successful authorization I get session in NSURLSession dataTask and cookies. I send cookies to js for next REST request with fetch, but get error of certificate. On native side all requests works fine. I'm just wondering if anybody can give an advice how to solve that problem, I think that with fetch I'm just losing my current session or something like that.
