I'm using openpgp.js in my chrome extension, and sendResponse that sends the response to the content script from decryptMessage is NOT working:
openpgp.decryptMessage(key, message).then(function(plaintext) {
    var res = sendResponse({result: "test"});
})
But it works inside the encryptMessage function:
openpgp.encryptMessage(publicKey.keys, base64Message).then(function(pgpMessage) {
    sendResponse({result: pgpMessage});
})
In the background console there are no errors, I have no clues why this is happening.
The entire onMessage handler:
function handleMessageEvent(request, sender, sendResponse) {
    console.log('just-encrypt');
    if(request.data.type == 'decrypt')
    {
        var key = openpgp.key.readArmored(request.data.privateKey);
        console.log(key);
        if(key.keys.length > 0)
        {
            key = key.keys[0];
            key.decrypt(request.data.password);
            var message = openpgp.message.readArmored(request.data.message);
                console.log('decrypt message');
                openpgp.decryptMessage(key, message).then(function(plaintext) {
                    console.log('decrypted');
                    sendResponse({result: 'test'});
                }).catch(function(error) {
                    console.log(error);
                });
        }
        else
        {
            chrome.extension.getBackgroundPage().console.log("no accessible keys found");
        }
      return true;
}
