Cordova-plugin-firebasex: Error when adding ios platform

[willxw8]

I put the GoogleService-Info.plist in the root folder, and add this node to config.xml:
<resource-file src="GoogleService-Info.plist"/>
then run the command "cordova platform add ios", I get this error:

Error during processing of action! Attempting to revert...
Failed to install 'cordova-plugin-firebasex': CordovaError: Uh oh!

If I delete the node from the config.xml, I can add the ios platform successfully, but the GoogleService-Info.plist file is not mine, it is a default placeholder from the plugin.

Do not add <resource-file src="GoogleService-Info.plist"/> to your config.xml - simply put the file in the root directory of the project and the plugin will pick it up.
