Functions predeploy error: Command terminated with non-zero exit code1

Question

I am following the following tutorial to deploy fulfillment on Google Action (it's for setting up firebase, at this point). However, when I do: firebase deploy --only functions in my cmd, I get an error: Functions predeploy error: Command terminated with non-zero exit code1. At first, I modified $RESOURCE_DIR to %RESOURCE_DIR% in my firebase.json since I'm using Windows. This reduced the number of errors I had drastically, but I still have the aforementioned one. Any ideas? The output error is shown here: Error Image
