invalid url causing crash in ios

[akshgods]

Bug description:

If we pass invalid url we are getting crash

actual url: https://www.hindustantimes.com/ht-img/img/2024/03/27/550x309/Akshay_Kumar_1711524357605_1711524357751.jpg

invalid url which causing crash: '%3Ca%20_blank%20href=https://www.hindustantimes.com/ht-img/img/2024/03/27/550x309/Akshay_Kumar_1711524357605_1711524357751.jpg'

Error handling functions not returning anything.

 onError={(e) => {
            console.log('onError:: ', e);

          }}
          onHttpError={(e) => {
            console.log('onHttpError:: ', e);

          }}
          renderError={(e) => {
            console.log('renderError:: ', e);
          }}

To Reproduce:

Reproduce is simple, just use this url in your webview url:

url={'%3Ca%20_blank%20href=https://www.hindustantimes.com/ht-img/img/2024/03/27/550x309/Akshay_Kumar_1711524357605_1711524357751.jpg'}

now open webview you will get application getting crash.

Expected behavior:

it should not get crashed , it will throw error in one of error handling function.

 onError={(e) => {
            console.log('onError:: ', e);

          }}
          onHttpError={(e) => {
            console.log('onHttpError:: ', e);

          }}

let me know what changes required or what we can do it to solved this?

• OS: Mac
• OS version: 13.2.1 (22D68)

@akshgods can you check issue is reproducible on latest version?

[akshgods]

@netmaxt3r yes confirmed with latest available version.

code to test:

<WebView source={{ uri: '3Ca%20_blank%20href=https://reactnative.dev/' }} 
       style={{ flex: 1 }}
       onError={(e) => {
        console.log('onError:: ', e);
      }}
      onHttpError={(e) => {
        console.log('onHttpError:: ', e);
      }}
      renderError={(e) => {
        console.log('renderError:: ', e);
      }}
       />

Environment:

OS: Mac OS version: 13.2.1 (22D68) "react-native": "0.73.6", "react-native-webview": "^13.8.5"

I am getting different results.

on iOS its just console.warn with Error opening URL: [Error: Unable to open URL: ....

on Android it does call onError with nativeEvent {"canGoBack": false, "canGoForward": false, "code": -2, "description": "net::ERR_NAME_NOT_RESOLVED", "loading": false, "target": 3, "title": "", "url": "http://3ca%20_blank%20href%3Dhttps//reactnative.dev/"} followed by two calls to renderError with null error

In either case app does not crash

[akshgods]

@netmaxt3r but im getting same error as i sent before.

but im not getting warning , can you share your code and url used?

also send react native version and plugin version used

[akshgods]

@netmaxt3r i understand you code diffrence

you used http:// in starting of url

just use this without http:

source={{ uri: '3Ca%20_blank%20href=https://reactnative.dev/' }}

[netmaxt3r]

@akshgods i havent added http protocol, it is added by android as the url is malformed it cannot detect the protocol, where as in ios it defaults to file protocol to relative path as seen in the warning

    return (
      <WebView source={{ uri: '3Ca%20_blank%20href=https://reactnative.dev/' }}
               style={{ flex: 1 }}
               onError={(e) => {
                 console.log('onError:: ', e.nativeEvent);
               }}
               onHttpError={(e) => {
                 console.log('onHttpError:: ', e);
               }}
               renderError={(e) => {
                 console.log('renderError:: ', e);
               }}
      />
    );

    "react": "18.2.0",

    "react-native-webview": "^13.8.5"
  }
