Solved

1. Clone the Github repo
2. Run the following commands

   cd functions && npm install && cd ..

    

3. Run this replacing your Firebase project-id and follow the prompts

   firebase ext:install . --project cproject-id]

    

4. Run this and accept 

   firebase deploy --only extensions

    

Worked here as well! Many thanks @simone. 

Thanks for posting this. I cannot for the life of me get this to install, I have the same error as you.

I can clone the repo and run 

cd functions && npm install && cd ..

without any issue. It does appear that its trying to create a new project though, instead of using my existing project when I run 

firebase ext:install . --project tproject-id]

Which then causes firebase deploy --only extensions to produce the error:

Error: Request to https://cloudresourcemanager.googleapis.com/v1/projects/revenuecat-xxxx had HTTP Error: 403, The caller does not have permission

Any thoughts?
 

Hi! Had the same, but when I changed (renamed) the project in the file below to my project, it succeeded:

firestore-revenuecat-purchases/extensions/firestore-revenuecat-purchases.env

​@mitchel-32fd79 Interesting, my env file, doesn’t have anything mentioning my project other than REVENUECAT_SHARED_SECRET. Did you have  PROJECT env var?

Hi ​@mb-3aced2 ! I went back to the project to verify, I’m sorry I shared the wrong file. It was in the ‘.firebaserc’ which is an hidden file in the main ‘firestore-revenuecat-purchases’ folder. There I changed the project and was able to deploy the extension. It is now working fine.

cd functions && npm install && cd ..

firebase ext:install . --project tproject-id]

Here is the source of error and solution for it: 
Default project value of downloaded extension is revenuecat-156XXXXXX. You need to change this value to your own project name.

1.Open the downloaded directory  in Vscode, Atom Text editor or any type of programming IDE.

2.Then execute ctrl+shift+F or command+shift+f for searching “revenuecat-156755”. 
It will list all files that includes this value. 

3.Change it with your project name then execute below command again, everything will be fixed; (firebase deploy --only extensions)

firebase deploy --only extensions

THEN IT WILL BE FIXED. Succesful output will look like this.
 

Why is this broken? Can someone at RevenueCat address?

What is the issue for you, which error are you getting, did you tried to 2 preferred solutions?

Same error as OP. The preferred solution is directly installing through Firebase Extensions web interface

Yes it would be good, you can fix it by manually deploying the code while waiting for bug fix. I suggest you to try the fix I posted. We are in the age of accelerationism unless you are in Europe . I just wrote a custom webhook handler for all events to manage custom user/credit system.

After getting this error, I just pressed the reinstall button and the installation got though this time. However, the function is still not deployed: “Function deployment failed. Try again.”

I’ve been trying to get this to work but to no success.
I contacted customer support and today I got this response from them, hopefully it’ll be sorted out in a few days.

“Hey there!
 
Thanks for reaching out. This is an issue we're aware of and currently working on a fix - we've published a new version that is currently under review, and this should be approved within a few days. I can keep you updated once this version is available!

Do we know what version is the fixed version? I see 0.1.14 is the current version.

@Anybody that sees this thread: if you see that the Firebase-RevenueCat extension is updated/live please ping this thread. Thanks

Also running into this issue. Hoping this is fixed soon.
