# Bug Report
## Problem
When I use ServiceWorker, the browser gives an error:
`TypeError: Failed to register a ServiceWorker for scope
('https://localhost/') with script ('https://localhost/service-worker.js'): An
unknown error occurred when fetching the script.`
### What is expected to happen?
The browser successfully registered ServiceWorker
### What does actually happen?
The browser gives an error:
TypeError: Failed to register a ServiceWorker for scope
('https://localhost/') with script ('https://localhost/service-worker.js'): An
unknown error occurred when fetching the script.
## Information
<!-- Include all relevant information that might help understand and
reproduce the problem -->
I used Cordova version 10.0 to create an offline web game, which provides
the WebViewAssetLoader class to access local web pages using HTTPS URLs.
But for the convenience of users to replace files, I want this webpage to
display files stored in the external directory of the phone. The directory
address is equivalent to 'cordova.file.externalApplicationStorageDirectory', so
I made some modifications to the source code of CordovaLib.
The webpage display was successful, but the registration of ServiceWorker
failed. After debugging, I found that the shouldInterceptRequest method of the
SystemWebViewClient class cannot intercept the registration of ServiceWorker.
Perhaps this is the reason for the registration failure.
### Command or Code
<!-- What command or code is needed to reproduce the problem? -->
Modify 'java/org/apache/cordova/engine/SystemWebViewClient.java' in the
CordovaLib folder as follows:
```java
// Replace this sentence with all the following code
// InputStream is =
parentEngine.webView.getContext().getAssets().open("www/" + path,
AssetManager.ACCESS_STREAMING);
AssetManager assetManager = parentEngine.webView.getContext().getAssets();
InputStream is;
// The path originally set by Cordova
String[] split = ("www/" + path).split("/");
// Get the folder where the original path is located
String[] newSplit = Arrays.copyOfRange(split, 0, split.length - 1);
// All files and folders in the folder where the original path is located
List<String> list = Arrays.asList(assetManager.list(String.join("/",
newSplit)));
if (list.contains(split[split.length - 1])) {
is = assetManager.open("www/" + path, AssetManager.ACCESS_STREAMING);
} else {
File file = new File(
parentEngine.webView.getContext().getExternalFilesDir(null).getParentFile(),
path
);
is = new FileInputStream(file);
}
```
