Fwd: [Bug] `credential fill` prints incomplete bearer credential

Hi. Is this a bug in git version 2.47.1? Or am I using it incorrectly?

# erase existing example.com credentials
printf "host=example.com\nprotocol=https\n" | git -c
credential.helper= -c credential.helper=cache credential reject
# store bearer token with expiry in far future in credential-cache
printf "host=example.com\nprotocol=https\nauthtype=bearer\ncredential=letmein\npassword_expiry_utc=2147483640\n"
| git credential-cache store
# try to retrieve credential
printf "host=example.com\nprotocol=https\n" | git -c
credential.helper= -c credential.helper=cache credential fill

Expected output (complete credential):

protocol=https host=example.com authtype=bearer credential=letmein password_expiry_utc=2147483640

Actual output (incomplete credential, no prompt for username or password):

protocol=https host=example.com password_expiry_utc=2147483640
