[[__NSArrayM insertObject:atIndex:]: object cannot be nil] [Cordova-Ios] App crash with SSL pinned active

[FranciscoVega2]

Hi, I'm having a problem similar to issue #173, but that one is closed. I hope you can help me, please.

Describe the bug
When I'm trying to make a POST request, my app crashes due to an NSException. This works fine on Android with the same code and .cer file.

System info

• affected HTTP plugin version: [3.3.1]
• affected platform(s) and version(s): [ iOS 14.2]
• affected device(s): [ iPhone 6 plus]
• cordova version: [11.1.0]
• cordova platform version(s): [ ios 6.3.0, android 10.1.2]

Minimum viable code to reproduce
const options = {
method: 'post',
data: { id: 12, message: 'test' },
headers: { Authorization: 'OAuth2: token' }
};

cordova.plugin.http.sendRequest('https://google.com/', options, function(response) {
// prints 200
console.log(response.status);
}, function(response) {
// prints 403
console.log(response.status);

//prints Permission denied
console.log(response.error);
});

I have the same problem, it happens to me sometimes not always, when I make a post request the ios app crash, on android it works fine.

I make the request as: http.post()

The problem may lie in the "setServerTrustMode" function. If I use the following code, there will be an error.

cordova.plugin.http.setServerTrustMode('pinned', function () {
    cordova.plugin.http.get(url, $.extend(data, obj2), {}, function (response) {
        console.log(response)
    }, function (response) {
        if (response.status != -7) {
            alert(response.error);
        }
    });
}, function () {
    showAlert('err');
});	

If I use the following code, it can run normally.

cordova.plugin.http.get(url, $.extend(data, obj2), {}, function (response) {
    console.log(response)
}, function (response) {
    if (response.status != -7) {
        alert(response.error);
    }
});

However, I cannot determine if it's a problem with the certificate path or a plugin issue. I have tried placing the certificate in various paths, but the error still occurs.

I found the reason, it's an SSL issue.

The server.cer file works on Android but not on iOS.
It's because the server.cer file is not correctly DER encoded.

You can refer to the following link to convert the cer file to DER encoding.
