Summary

There is a task #2535 with the same issue that was closed 2 months ago. I wasn't sure if it was possible to reopen a closed task.

Anyway, after upgrading to the new version:
@salesforce/cli/2.70.7 win32-x64 node-v22.11.0
I get the message in the topic for every sf command I run.

I also tried downgrading to version 2.69.14 and still the same error.

Steps To Reproduce

Run sf command

@yaniv3109 could you try uninstalling and re-installing (from the json info it seems you are using the Windows installer?)
I wonder if it's related to scripts that launch sf after an update via sf update.

[yaniv3109]

Hi,
I tried doing this, it didn't help.
I also installed the version that was written for which the issue was resolved 2.69.14.

[cristiand391]

Ok, I got a windows machine so I'll give it a try tomorrow.

I've tried install from npm using node v22.12.0 and don't get the warning.
Installed latest stable (v2.71.6) using the windows installer, no warning.
Updated to stable-rc via sf update stable-rc, still no warning.

I've looked at all the sf entrypoints for these 3 cases and can't see how it would get into a path where the warning shows up.

When you uninstalled the CLI, did you remove the files under LOCALAPPDATA like mentioned here:
https://developer.salesforce.com/docs/atlas.en-us.sfdx_setup.meta/sfdx_setup/sfdx_setup_uninstall.htm

these folders keep some update files that the sf entrypoint might be sourcing.

• I launch Windows Sandbox to get a fresh environment on Windows 11
• I go to https://developer.salesforce.com/tools/salesforcecli , Download for Windows x64, and install with default options
• I launch cmd and run sf version
