GER region returns no data while docs/config reference DE-LU (invalid for HACS integration)

Configuration

sensor:
  - platform: nordpool
    # Country/region to get the energy prices for.
    region: "GER"

    # Override HA local currency used to fetch the prices from the API.
    currency: "EUR"

    # Add Value Added Taxes (VAT)?
    VAT: True

    # Energy price rounding precision.
    precision: 3

    # Percentage of average price to set the low price attribute
    # low_price = hour_price < average * low_price_cutoff
    low_price_cutoff: 0.95

    # Display price in cents instead of (for example) Euros.
    price_in_cents: false

    # Price displayed for MWh, kWh or Wh
    price_type: kWh

    # Template to specify additional cost to be added to the tariff.
    # The template price is in EUR, DKK, NOK or SEK (not in cents).

Describe the bug

When using the HACS Nord Pool integration with region GER, the sensor entity is created successfully, but no price data is returned.

The sensor state remains unknown and all price-related attributes (today, raw_today, current_price, min, max, etc.) stay null, even after multiple restarts and waiting for data updates.

At the same time, GER is the only valid region option for Germany in this integration.
Using DE-LU (which is commonly referenced for Germany in Nord Pool context and other Home Assistant integrations) is not accepted and causes a configuration validation error.

This results in a confusing and blocking situation:

DE-LU is commonly referenced but cannot be configured

GER is accepted but does not return any data

It is currently unclear which region code should be used to retrieve German Nord Pool spot prices with this integration.
