Firebase function in vue project won't deploy to google cloud - firebase

Question

I have a vue project. It has a firebase function. I was able to deploy the function to google cloud once. But trying to deploy it later, I find I'm unable to.
Here is the console output from Visual Studio Code:
PS C:\udemy\vue-firebase\geo-ninjas> firebase deploy --only functions
=== Deploying to 'g-s-geo-ninjas'...
i deploying functions
Running command: npm --prefix "$RESOURCE_DIR" run lint
functions# lint C:\udemy\vue-firebase\geo-ninjas\functions
eslint .
functions: Finished running predeploy script.
i functions: ensuring necessary APIs are enabled...
functions: all necessary APIs are enabled
i functions: preparing functions directory for uploading...
i functions: packaged functions (38.34 KB) for uploading
functions: functions folder uploaded successfully
i functions: updating Node.js 6 function checkAlias(us-central1)...
! functions[checkAlias(us-central1)]: Deployment error.
Error setting up the execution environment for your function. Please try > deploying again after a few minutes.
Functions deploy had errors with the following functions:
checkAlias
To try redeploying those functions, run:
firebase deploy --only functions:checkAlias
To continue deploying other features (such as database), run:
firebase deploy --except functions
Error: Functions did not deploy properly.
PS C:\udemy\vue-firebase\geo-ninjas>
When I look at the logs in the firebase console, I see this:
{"#type":"type.googleapis.com/google.cloud.audit.AuditLog","status":{"code":13,"message":"INTERNAL"},"authenticationInfo":{"principalEmail":"junk.mail291276#gmail.com"},"requestMetadata":{"requestAttributes":{},"destinationAttributes":{}},"serviceName":"cloudfunctions.googleapis.com","methodName":"google.cloud.functions.v1.CloudFunctionsService.UpdateFunction","resourceName":"projects/g-s-geo-ninjas/locations/us-central1/functions/checkAlias"}
I widdled down my checkAlias function to the bare minimum that would function:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp();
exports.checkAlias = functions.https.onCall(data => {});
...and this still won't deploy.
I've ran eslint and this has no lint errors. When I run this locally, it works.
Why would I be getting these errors when trying to deploy my firebase function?
