Firebase Functions Deployment Fails Due to Cloud Build and Artifact Registry Permissions

Want to use over 200+ MCP servers inside your coding tools like Cursor?
I created a new Firebase project and copied the sample v1 functions from the Firebase documentation. However, when I run the deploy command with
BASHfirebase deploy --only functions
I'm getting the following error:
BASHGen1 operation for function projects/xxx/locations/us-central1/functions/addMessage failed: Build failed: Build error details not available.Please check the logs at https://console.cloud.google.com/cloud-build/builds;region=us-central1/xxx.

Functions deploy had errors with the following functions: addMessage(us-central1) makeUppercase(us-central1) i functions: cleaning up build files... ⚠ functions: Unhandled error cleaning up build images. This could result in a small monthly bill if not corrected. You can attempt to delete these images by redeploying or you can delete them manually at https://console.cloud.google.com/gcr/images/xxx/eu/gcf https://console.cloud.google.com/gcr/images/xxx/us/gcf Error: There was an error deploying functions: - Error Failed to create function addMessage in region us-central1 - Error Failed to create function makeUppercase in region us-central1
The error message at the provided URL is as follows:
BASHStep #2 - "build": ERROR: failed to create image cache: accessing cache image "us-central1-docker.pkg.dev/ki-beratung-8af95/gcf-artifacts/add_message/cache:latest": connect to repo store "us-central1-docker.pkg.dev/xxx/gcf-artifacts/add_message/cache:latest": GET https://us-central1-docker.pkg.dev/v2/token?scope=repository%3Axxx%2Fgcf-artifacts%2Fadd_message%2Fcache%3Apull&service=: DENIED: Permission "artifactregistry.repositories.downloadArtifacts" denied on resource "projects/xxx/locations/us-central1/repositories/gcf-artifacts" (or it may not exist)
The logs show an error image similar to this:
This is supposed to be a standard Firebase Cloud Function deployment. Why is Cloud Build, Artifact Registry, and Cloud Logging involved now? For years, this process just worked. I've already seen a couple of responses suggesting permission adjustments, and I would appreciate further insights into what has changed and how to permanently fix it.

Below is an explanation and how to resolve the issue.
Why Are These Services Involved?
Even though you’re deploying Firebase Cloud Functions, the deployment process for Gen 1 functions now involves several Google Cloud services:
- Cloud Build: Used under the hood to build a container image for your function.
- Artifact Registry: Caches the build images and serves as storage for artifacts.
- Cloud Logging: Captures detailed logs during the build/deployment process.
This architecture change lets Firebase functions leverage containerization and build caching, even if it’s new to you. In previous deployments, these steps were hidden, so it might seem like “something changed.”
What’s Causing the Error?
The error message indicates a permission issue when attempting to download the cached image. Specifically, the Cloud Build process is getting denied the permission:
artifactregistry.repositories.downloadArtifacts
This could be because:
- The default service account used by Cloud Build (usually
<PROJECT_NUMBER>@cloudbuild.gserviceaccount.com) does not have the Artifact Registry Reader role. - The Artifact Registry repository (
gcf-artifacts) might not be configured as expected.
How to Fix It
You need to grant the Cloud Build service account permission to download artifacts from the relevant Artifact Registry repository. For example, you can run the following command (replace <PROJECT_ID> and <PROJECT_NUMBER> with your project’s values):
BASHgcloud projects add-iam-policy-binding <PROJECT_ID> \ --member=serviceAccount:<PROJECT_NUMBER>@cloudbuild.gserviceaccount.com \ --role=roles/artifactregistry.reader
This command assigns the Artifact Registry Reader role to the Cloud Build service account, which should resolve the "permission denied" error during the build step.
Next Steps
-
Grant the Role: Run the command above.
-
Re-deploy: After updating the permissions, deploy your functions again using:
BASHfirebase deploy --only functions -
Monitor Logs: If issues persist, check the linked Cloud Build logs for additional details.
This approach aligns with the current deployment process for Firebase Cloud Functions, which now relies on other GCP services.
By adding the necessary role, you should be able to successfully deploy your functions as before.

It turns out that I needed to add Artifact Registry Administrator role to my firebase service account under IAM.
After that a follow-up error happened that required me to change my organization policy under IAM/Organization-Policies regarding domain restricted sharing to be google-managed default instead of Inherit parent's policy.
I couldn't change that policy immediately because apparently I didn't have the permission to change the above policy. So I had to run the following command in cloud shell:
gcloud organizations add-iam-policy-binding YOUR_ORG_ID --member='user:YOUR_EMAIL' --role='roles/orgpolicy.policyAdmin'
After these two changes, I could deploy the function ✅
My guess is that the deployment process needs to assign a couple of additional permissions to itself, but it couldn't do it because of the restrictions.
Although my original question is hereby answered, I still don't understand why domain restricted sharing didn't start with google-managed default from the beginning :/
