PermissionError: [Errno 13] Permission denied: '.env'
, this is not coming from a flow but the prefect run itself, here is the stack trace:

Thanks for the stack trace — that helps. What’s happening: - When Prefect starts up, it builds its settings using pydantic-settings. As part of that, it will probe for a
.env
file in the current working directory. - Your traceback shows the error occurs while pydantic checks
Path('.env').is_file()
, which calls
os.stat('.env')
. A PermissionError here means there is something named
.env
in your current directory (a file, directory, or symlink) that your user cannot stat/access — even if you don’t intend to use it. Why you see this even if you “don’t have a .env”: -
.env
is a hidden name; you won’t see it without listing hidden files. - It could be a directory or a symlink with restrictive permissions (e.g., mode 000) or pointing somewhere you cannot access. - pydantic-settings tries to check if it’s a file and trips over the permission error before it can decide to ignore it. Quick ways to unblock: 1) Inspect what
.env
actually is and its permissions
Copy code
ls -lad .env
namei -l .env
stat .env
2) Fix or move it out of the way - If it’s a file you don’t need:
Copy code
mv .env .env.bak
- If it’s a directory with no execute bit (so you can’t stat it):
Copy code
chmod u+x .env
- If it’s a file with no read bit:
Copy code
chmod u+r .env
- If it’s a symlink, follow where it points (
namei -l .env
) and fix permissions on the target or remove the symlink. 3) Run the Prefect CLI from a different working directory - For example:
Copy code
cd ~
prefect config view
This avoids the problematic
.env
in your current project directory. Important note: - In Prefect 3.x there isn’t a setting/flag to disable
.env
probing altogether; it’s part of the settings bootstrap done by pydantic-settings. We can consider improving error handling here, but for now the remedies above are the practical approaches. If you can, please share: - Output of
ls -lad .env
and
namei -l .env
- Your current working directory (
pwd
) - Prefect version (
prefect version
) Docs for reference: - Settings and profiles in Prefect 3

@Marvin I am running prefect flow in a pod in kubernetes, is there a way to set working directory before the "prefect flow-run execute"?
m
thought for 145.1 seconds
Yes — for Kubernetes runs you can set the container working directory so the Prefect process starts in a safe path (and skips any problematic
.env
in the previous CWD). Recommended options: 1) Set workingDir in the Kubernetes work pool’s base job template - Get the default template:
Copy code
prefect work-pool get-default-base-job-template --type kubernetes > base.json
- Edit the container spec to add workingDir, e.g.:
Copy code
{
  "job_configuration": {
    "job_manifest": {
      "spec": {
        "template": {
          "spec": {
            "containers": [
              {
                "name": "prefect-job",
                "image": "{{ image }}",
                "imagePullPolicy": "{{ image_pull_policy }}",
                "env": "{{ env }}",
                "args": "{{ command }}",
                "workingDir": "/home/prefect"
              }
            ],
            "restartPolicy": "Never",
            "serviceAccountName": "{{ service_account_name }}"
          }
        }
      }
    },
    ...
  }
}
- Apply it to your work pool:
Copy code
prefect work-pool create "my-pool" --type kubernetes --base-job-template base.json --overwrite
2) Make workingDir configurable via job_variables (per-deployment) - In your base job template, parameterize the directory:
Copy code
"workingDir": "{{ working_dir }}"
- In your deployment call, set it:
Copy code
flow.from_source("<https://github.com/org/repo>", entrypoint="flows/my_flow.py:flow").deploy(
  name="my-deploy",
  work_pool_name="my-pool",
  job_variables={"working_dir": "/home/prefect"}
)
3) Set WORKDIR in your image or entrypoint - If you own the container image, set
WORKDIR /home/prefect
in the Dockerfile or add an entrypoint script that `cd`s before exec’ing the Prefect command. Any of these ensures the container starts in a directory that doesn’t contain a
.env
, so pydantic-settings won’t hit that PermissionError while probing for
.env
. References: - Customize job variables - Manage work pools If you share your current work pool name and whether you prefer a pool-wide default or per-deployment override, I can sketch the exact JSON or deployment snippet.
