Error: Could not find rules for the following storage targets: rules

[godrays]

Hi everyone,

I've been using Firebase for a while now and everything seems great, except for the fact that the storage.rules files can't be found when I attempt to deploy the rules. The firestore.rules files, however, deploy without any problems.

Is this a known problem? I couldn't find a solution for it.

Thank you for the help.

[REQUIRED] Environment info

firebase-tools 12.4.4
firebase 12.4.4
corepack 0.17.0
npm  9.5.1

macOS Ventura 13.4

[REQUIRED] Test case

Not sure what to put here.

[REQUIRED] Steps to reproduce

storage.rules file

rules_version = '2';

service firebase.storage
{
    match /b/{bucket}/o
    {
        match /test/{allPaths=**}
        {
            allow read: if true;
            allow write: if true;
        }
    }
}

firebase.json file

{
  "firestore": {
    "rules": "rules/firestore.rules",
    "indexes": "firestore.indexes.json"
  },
  "storage": {
    "rules": "rules/storage.rules"
  },
  ...

Note: I tried to put storage.rules in root folder as well but still didn't work.

rules file location

<project_root>/rules/firestore.rules
<project_root>/rules/storage.rules              

Command to deploy

firebase deploy --only storage:rules

[REQUIRED] Expected behavior

Deploying rules without an error.

[REQUIRED] Actual behavior

$ firebase deploy --only storage:rules

=== Deploying to 'xxxxxxxxxxxxxx'...

This issue does not seem to follow the issue template. Make sure you provide all the required information.

Hi @godrays, thanks for reaching out. Could you try running firebase deploy --only storage to see if this would deploy your Cloud Storage for Firebase rules? Here is the reference to the deploy commands.

[godrays]

It worked without it. Surprisingly, no need to add :rules argument.
Thank you for the link.

I did have the same issue like the author, deploying with "storage:rules" failed (despite an existing rules file) while deploying with only "storage" worked. Is "storage:rules" unsupported syntax or just a bug? Thanks!

I had to change my code from this:

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    // User-specific content
    match /user_uploads/{userId}/{allPaths=**} {
      allow read, write: if request.auth != null && request.auth.uid == userId;
    }
    
    // Public course materials
    match /course_content/{courseId}/{file} {
      allow read: if true;
      allow write: if request.auth != null && 
                   get(/databases/$(database)/documents/admins/$(request.auth.uid)).exists;
    }
  }
}

To this:

rules_version = '2';
service firebase.storage {
  match /b/{bucket}/o {
    match /user_uploads/{userId}/{file} {
      allow read, write: if request.auth != null && request.auth.uid == userId;
    }
  }
}

Then I use this based on users suggestion in this issue, $ firebase deploy --only storage, rules were updated in the storage console successfully without warnings, or below errors:

i firebase.storage: checking storage.rules for compilation errors...
! [W] 13:20 - Invalid function name: get.
! [W] 13:37 - Invalid variable name: database.

Thanks Devs.
