What is the cause of BRANCH SDK: Invalid "android-prefix" in <branch-config> in your config.xml error?

Question

I have recently incorporated branch's branch-cordova-sdk into my application. Now when I use ionic package to build my .apk file, ionic package fails with the following error:

BRANCH SDK: Invalid "android-prefix" in <branch-config> in your config.xml.

My Config.xml file uses the required options according to the docs and is as follows:

<?xml version='1.0' encoding='utf-8'?>
<widget id="com.test.project" version="0.0.1">

    <plugin name="branch-cordova-sdk" spec="^2.5.17" />
    <branch-config>
        <branch-key value="key_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" />
        <uri-scheme value="testApp" />
        <link-domain value="com.test.project" />
    </branch-config>

</widget>

I have also tried adding the option android prefix with a dummy value like this: without any success.

It is not clear to me what is going wrong here, any help would be appreciated.

I am using the following:

• branch-cordova-sdk : 2.5.17
• @ionic/cli-utils : 1.3.0
• CordovaCLI: 7.0.1
• Ionic CLI: 3.3.0
• @ionic/app-scripts : 1.3.7
• @ionic/cli-plugin-cordova : 1.3.0
• @ionic/cli-plugin-ionic-angular : 1.3.0
• Cordova Platforms : android 6.3.0-dev ios 4.3.1
• Ionic Framework : ionic-angular 2.0.1
