CiviGrant - Can't edit existing grants following move to Core Extension

Overview

When trying to edit an existing grant in CiviCRM of Civi versions 5.47.0 onwards, I am greeted with an error message.

Reproduction steps

Editing a Grant from a Contact Record:

1. Find any existing contact record that has an existing Grant, and navigate to the Contact Record -> Grants tab.
2. Press the "Edit" button.
3. Receive "Network Error Unable to reach the server. Please refresh this page in your browser and try again." status bounce message
4. Look at Watchdog / Error logs:

TypeError: Argument 2 passed to CRM_Grant_BAO_Grant::retrieve() must be of the type array, null given, called in /buildkit/build/user-prompts/vendor/civicrm/civicrm-core/ext/civigrant/CRM/Grant/Form/Grant.php on line 106 in CRM_Grant_BAO_Grant::retrieve() (line 75 of /buildkit/build/test/vendor/civicrm/civicrm-core/ext/civigrant/CRM/Grant/BAO/Grant.php) 

Editing a Grant from the "Find Grants" screen:

1. Navigate to the "Find Grants" screen
2. Press "Search"
3. Press "Edit" on any of the displayed Grants
4. Note the same behaviour presents as above.

Current behaviour

TypeError: Argument 2 passed to CRM_Grant_BAO_Grant::retrieve() must be of the type array, null given, called in /buildkit/build/user-prompts/vendor/civicrm/civicrm-core/ext/civigrant/CRM/Grant/Form/Grant.php on line 106 in CRM_Grant_BAO_Grant::retrieve() (line 75 of /buildkit/build/test/vendor/civicrm/civicrm-core/ext/civigrant/CRM/Grant/BAO/Grant.php) 

Expected behaviour

I should be able to edit a grant.
