React native axios crashing and werid behaviour - reactjs

Question

Axios is behaving weird on my react native webview if you have any idea how to solve or how i can track the problem it would be of much help.
On the onMessage of the webview i recieve the html of the website so i can get a specific link. I send the message when the user taps anywhere on screen.
Injected js:
var body_of_html = document.body;
body_of_html.addEventListener('click',function(e){
window.ReactNativeWebView.postMessage(document.documentElement.innerHTML)
},false);
Case 1
This doesnt console.log anything and after some time crashes the app.
onMessage={event => {
// console.log('asdas');
var regex = new RegExp('token=[a-zA-z0-9]+');
if (event.nativeEvent.data.toString().match(regex) != null) {
let asd =
'https://fvs.io/redirector?' +
event.nativeEvent.data.toString().match(regex);
axios.get(asd).then(rs => {
console.log(rs);
});
Case 2
This one works perfectly fine and logs "Anything".
onMessage={event => {
var regex = new RegExp('token=[a-zA-z0-9]+');
if (event.nativeEvent.data.toString().match(regex) != null) {
let asd =
'https://fvs.io/redirector?' +
event.nativeEvent.data.toString().match(regex);
axios.get(asd).then(console.log("Anything"));
As you can see from the above cases i am unable to get the response from the axios call. Which always after some time crashes the app. Am i doing something wrong on reciving the response ?
Edit: I think I know what might have caused my application to crash but this is just what I found after looking at the data consumed. The link i was sending to the axios.get was retriving bits of a video until it fully buffered. But the way my code was , it would do this action each time i tapped the screen. I guess at some point axios couldnt handle reciving 10x + videos at 1080p at the same time. Just to clarify my intention was just to get the redirection link i didnt know it would cause the video to buffer.

As in all promises, in order to debug the error, e.g. in cases where event.nativeEvent.data may be undefined, causing .toString() to throw error, use a catch block.
axios.get(asd).then(rs => {
console.log(rs);
}).catch(error => console.log("error from axios", error))
