Cannot run the project

[koravski]

Hi, I have trouble running the project. I've managed to deploy it but I get this error:
Access to fetch at 'https://us-central1-scrabble-16935.cloudfunctions.net/validateUser' from origin 'https://scrabble-16935.web.app' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.
VM1464:1 POST https://us-central1-scrabble-16935.cloudfunctions.net/validateUser net::ERR_FAILED
index.cjs.js:58 Uncaught (in promise) Error: internal at new e (index.cjs.js:58)
Any ideas on how to fix it?
Thanks.

Hi @koravski haven't visited my JS projects for a while, but I recently, the validate user function for another one of my project stopped working when I updated my project. This could be down to some update in Firebase Functions/Auth API. I will have another gander at it sometime this.

Just to make sure I have covered my basis here, functions need to import service keys to be able to access the database and perform admin duties. Did you add service keys to your project?

[koravski]

Yes, I did. I have added also:
project_owner_email in the service keys file.
I guess is something small I haven't done correctly, but not sure what is it.
When I try to create a game I get this as well:
Internal read error. TypeError: Cannot read property 'instances' of undefined, [object Object]
Any ideas what this might be?
Thanks.

PS I think it could be from my firebaseInit.js file. Could you share yours without the keys?
