I uploaded a CSV file directly to Looker Studio and it’s working fine in my report. However, I cannot download or access the original file that Looker Studio automatically stored in Google Cloud Storage. I’m getting 403 errors on everything.
Setup
-
Data source: CSV uploaded directly to Looker Studio (47.2 MB file)
-
Report access: I have full edit access to the report
-
GCP account: (PII Removed by Staff) with 3 active projects
The Problem
Looker Studio created this bucket automatically:
gs://looker-studio-data-import-e028e878-3dc1-4908-9bc1-4908-9bc1-38df0a596b05
When I check the bucket details with gsutil ls -L -b, I see:
-
ACL: [] (empty!)
-
Default ACL: [] (empty!)
This means the bucket was created without any permissions for anyone, including me.
What I’ve Tried
Download from Cloud Storage console → 403 Forbidden
gsutil cp command → 403: storage.objects.get denied
gsutil iam ch to add permissions → 403: storage.buckets.getIamPolicy denied
Export CSV option in Looker Studio → doesn’t exist for uploaded CSVs
Questions
-
Is this a known bug? Why would Looker Studio create a bucket with empty ACLs?
-
How can I access my own data? The file is mine, but I’m completely locked out
-
Is there a workaround to export the complete dataset from Looker Studio?
-
Who actually owns this bucket? It doesn’t appear in any of my GCP projects
Workarounds I Found
The only way I can get data out is by manually exporting each visualization/chart as CSV, but this is impractical for large datasets and doesn’t give me the raw data.
