BrainstemStudio opened a new issue #1119:
URL: https://github.com/apache/cordova-ios/issues/1119
# Bug Report
We are busy reviewing our apps to get ready for iOS 15 changes. We have
noticed when using a basic JS fetch and supplying custom headers the encounters
an error. This is problematic especially if the the fetches require headers
such as tokens, authorization ect.
This appears to only occur when using the scheme and host name options.
```
<preference name="scheme" value="http" />
<preference name="hostname" value="localhost" />
```
## Problem
**Web Error**
`Failed to load resource: WebKit encountered an internal error`
**XCode Error**
```
[Process] 0x128ad1000 - NetworkProcessProxy::didClose (Network Process 0
crash)
[assertion] Error acquiring assertion: <Error Domain=RBSAssertionErrorDomain
Code=2 "Specified target process does not exist"
UserInfo={NSLocalizedFailureReason=Specified target process does not exist}>
```
### What is expected to happen?
At least a success or catch error should return on the js fetch
### What does actually happen?
Xcode returns a error and the fetch does not execute
