Fwd: error: 'submodule' does not have a commit checked out

I used to update last commit with new changes:

git commit --amend .

The project has several submodules:

 e116c89a58af750421d82ece13f80516d2bde02e extra/wolfssl/wolfssl
(v4.3.0-stable-596-ge116c89a5)
a746c3af449a8754e78ad7971e59e79af7957cdb libmariadb (v3.1.3-121-ga746c3a)
b6b02ed516f92055127d416370799d91a82754ea
storage/columnstore/columnstore (columnstore-1.5.3-1-14-gb6b02ed5)
-d172e86c16224b4e0229ca6f102e662a2315aeff storage/maria/libmarias3
-bba5e7bc21093d7cfa765e1280a7c4fdcd284288 storage/rocksdb/rocksdb
-ae4e58ba031587039c8830f2f8ca51fa9fb7d6eb wsrep-lib

Now it fails with this message:

git commit --amend .
error: 'storage/maria/libmarias3' does not have a commit checked out
fatal: updating files failed

How to use amend without specifying explicit paths without
initializing submodules? I don't need to amend submodules and would
prefer them ignored in my commits.

git --version
git version 2.27.0

Works as expected in 2.19.1
