(iOS) SyntaxError in plugin JS console messages

[webcodepl]

My configuration:

Model: iPhone X
Version: iOS 13.4.1

Model: MacBook Pro 13
Version: 10.15.4

Cordova 9.0.0 (cordova-lib@9.0.1)

cordova-custom-config 5.1.0 "cordova-custom-config"
cordova-plugin-androidx 1.0.2 "cordova-plugin-androidx"
cordova-plugin-androidx-adapter 1.1.1 "cordova-plugin-androidx-adapter"
cordova-plugin-customfcmreceiver 1.0.0 "Custom FCM Receiver"
cordova-plugin-dialogs 1.3.2-dev "Notification"
cordova-plugin-enable-multidex 0.2.0 "Enable Multidex"
cordova-plugin-firebasex 9.1.1 "Google Firebase Plugin"
cordova-plugin-whitelist 1.3.4 "Whitelist"

Xcode Version 11.4.1

Problem:

After receiving message i get error on console: SyntaxError: Unexpected EOF. I am sending message using:
npm run-script send -- --message=ios_data_notification.json --token="..."

I was trying also versions 8.0.1, 9.1.1-cli, compiling from xcode and xcodebuild, still the same error.

I can repro this issue:
It's actually an issue with escaping of line endings for Javascript when sending log messages from the native iOS implementation to the Cordova Webview for display in the JS console.

For example, an expected log message would be:

console.log("FirebasePlugin[native]: didReceiveRemoteNotification: {\
    aps =     {\
        \"content-available\" = 1;\
    };\
    \"gcm.message_id\" = 1589924900140911;\
    \"key_1\" = \"Data for key one\";\
    messageType = data;\
    \"notification_body\" = \"Data message body\";\
    \"notification_foreground\" = true;\
    \"notification_ios_badge\" = 1;\
    \"notification_ios_sound\" = \"blackberry.caf\";\
    \"notification_title\" = \"Data message title\";\
}")

but the actual string being generated is:

console.log("FirebasePlugin[native]: didReceiveRemoteNotification: {
    aps =     {
        \"content-available\" = 1;
    };
    \"gcm.message_id\" = 1589924900140911;
    \"key_1\" = \"Data for key one\";
    messageType = data;
    \"notification_body\" = \"Data message body\";
    \"notification_foreground\" = true;
    \"notification_ios_badge\" = 1;
    \"notification_ios_sound\" = \"blackberry.caf\";
    \"notification_title\" = \"Data message title\";
}")

i.e. no escaping backslashses at the end of lines, resulting in the console error SyntaxError: Unexpected EOF.

@dpa99c it seems you accidentally reverted this change in: 116f5ce

could you plz merge it again?

[angjelkom]

@dpa99c I tried your fix but it doesn't seem to work fully I get: SyntaxError: Invalid escape in identifier: 'summary\' (my payload data contains object with key summary)

[angjelkom]

@dpa99c the fix doesn't work I am getting: SyntaxError: Invalid escape in identifier: 'summary\' my push data contains an object which has the key summary

[dpa99c]

I will look at it again when I have some time

[dpa99c]

@EchoNox It looks like your keys are wrapped in single quotes:

SyntaxError: Invalid escape in identifier: 'summary'

which is invalid JSON.

Hence the Firebase Admin SDK will not allow a message to be sent containing single-quoted keys so I'm unable to reproduce your issue.

Can you confirm whether your keys are double-quoted or single-quoted?
In fact, if possible, can you supply a sample notification message which is causing you this issue.

I believe this is resolved by #430
