Origin capacitor://localhost is not allowed by Access-Control-Allow-Origin - ios

Question

I want download file on my ionic mobile app from amazon S3 but I have this issue Origin capacitor://localhost is not allowed by Access-Control-Allow-Origin.
So I add "capacitor://localhost" on my CORS configuration on amazon S3 like this :
[
{
"AllowedHeaders": [
"*"
],
"AllowedMethods": [
"HEAD",
"GET",
"PUT",
"POST",
"DELETE"
],
"AllowedOrigins": [
"*",
"capacitor://localhost"
],
"ExposeHeaders": []
}
]
but I have always the same issue.
My download function :
async downloadResource(filename: string) {
try {
this.url = this.changeSpecialCharacter(this.urlFolder + filename);
let extention = this.getFileExtension(filename);
filename = this.getFileName(filename);
if (!filename.includes(extention)) {
filename = filename + '.' + extention;
}
if (!filename) filename = this.url.split('\\').pop().split('/').pop();
const response = await fetch(this.url, {
headers: new Headers({
'Origin': 'capacitor://localhost'
}),
mode: 'cors'
});
console.log(' response '+JSON.stringify(response));
const blob = await response.blob();
const blobUrl = URL.createObjectURL(blob);
console.log(' blobUrl '+JSON.stringify(response));
const result = await Filesystem.writeFile({
path: filename,
data: blobUrl,
directory: Directory.Documents,
encoding: Encoding.UTF8
});
console.log('File written', result);
} catch (e) {
console.error('error fetch '+e);
}
}
I test also with const response = await fetch("https://file-examples.com/storage/feeb72b10363daaeba4c0c9/2017/10/file_example_JPG_100kB.jpg", {mode: 'cors'}); I have the same issue. So the problem is from the device
