[Bug]: PAC CLI Reset or Create Failure: macroRegion 'unitedstates' is not valid

Is this bug related to Code Apps?

No

Description

This occurs across multiple environments within the same tenant.

The issue appears to be related to tenants using the new Macro Region Geography provisioning model, where the backend expects a macro-region value rather than the legacy unitedstates region identifier.

pac admin reset --environment https://Example.crm.dynamics.com/
--domain Example --name Example Environment
--purpose This is an example environment configuration.

pac admin create --type 'sandbox'
--domain Example `
--name Example Environment

Error: macroRegion 'unitedstates' is not valid

Extension Version

2.11.2.0

VS Code Version

1.136.1

VS Code Channel

Stable

Steps to Reproduce

1. Open Visual Studio Code
2. In terminal enter pac admin reset --environment https://Example.crm.dynamics.com/ --domain Example --name Example Environment --purpose This is an example environment configuration.

or pac admin create --type 'sandbox' --domain Example --name Example Environment

Expected Behavior

Environment is reset or created

Actual Behavior

Error: macroRegion 'unitedstates' is not valid

Additional Context

This is new in the last week or two.

Start by reproducing the failure with the pac admin reset and pac admin create commands described in the issue. Trace how these commands determine the macro-region for tenants using the new Macro Region Geography provisioning model. Done means both operations succeed for affected tenants without the macroRegion 'unitedstates' is not valid error.
