cordova-plugin-background-mode plugin used to work, but now the build crashes and the log appears to point to this plugin

cordova-plugin-background-mode plugin used to work in phonegap. I have had Android apps that have run for years with it. Now when I try a phonegap build, the same code that used to work, now will not create an APK. See log.

I have researched online, but no one else seems to be having this problem.

This is the last several lines in the Build Log:

Error messages are in the log file. I am using the online Phonegap build -- not the Cordova CLI.

I solved the problem by reinstalling this plugin:

cordova plugin rm cordova-plugin-background-mode
cordova plugin add cordova-plugin-background-mode

Had to add these lines in config.xml:

<preference name='phonegap-version' value='cli-9.0.0' /> <preference name='pgb-builder-version' value='1' /> <preference name="android-targetSdkVersion" value="28" />

This not only makes things work, it is also compliant with Google Play Store's new target API requirements. All apps must support Android 9.0 (API level 28) by November 1st.
