Error in downloading gcloud project’s IAM policy

May 8, 2023

I am nee to google cloud and trying to explore. I tried to download my project’s IAM policy as a CSV file however I am encountering an error:

(gcloud.projects.get-iam-policy) Format [csv] requires a non-empty projection.

Can someone help me with this?

Run the command —format csv flag, expecting to extract the iam policy in csv file. Error mentioned showed.

>Solution :

Error is expected when you try to extract IAM policy in csv format as there’s no built-in functionality for this. However you can instead opt to use json to extract the policies then just convert it to csv after.
Enter the below commands in the shell:

$gcloud projects get-iam-policy your-project --format json > iam.json

This will output a json file with the format:

{
   "bindings": [
   {
       "members": [
       ...
       ],
       "role": "..."
   },
   {
       "members": [
           "...",
           "..."
       ],
       "role": "..."
   }
   ],
   "etag": "...",
   "version": ...
}

Hope this helps.
