Unable to post message to file://. Recipient has origin null.

I have an application written on vue. It worked until I switched to WkWebView. Then I started to get this error - Unable to post message to file: //. Recipient has origin null. Installing your plugin did not help. Do I have to do anything else in my code?

I'm getting the same error. Someone fixed it?

I had a similar problem, searched everywhere and couldn't find an answer, but this worked. Either create a plugin that does the following or add it to your existing code

Add the following to your header:

import <WebKit/WebKit.h>

import <Cordova/CDV.h>

Then the following to your code:

NSLog(@"Updating webview to allow local file access"); WKWebView wkWebView = (WKWebView ) self.webViewEngine.engineWebView [wkWebView.configuration.preferences setValue:@YES forKey:@"allowFileAccessFromFileURLs"];

To clarify the error I was getting had to do with a cross origin issue due the the null origin in the request from file:// so I am not 100 percent sure that this will work but it might be worth a try
