Restored Database Size is 0.

Hello, first of all, thank you for providing such a great tool. I have been using it well.

Recently, I encountered an issue when trying to restore a database from a remote storage to my local environment. The issue is restored database's size is 0. My setup is as follows:

ruby 3.3.1
rails 7.1.3.2
litestream_ruby 0.10.1
litestream_rails 0.4.1
I am using CloudFlare R2 Storage as the remote storage.

The following commands provide normal results:

bin/rails litestream -- --database=storage/development.sqlite3

name  generation        lag     start                 end
s3    7cb3016377add0bf  -3m2s   2024-07-07T12:45:42Z  2024-07-07T12:45:43Z

name  generation        lag     start                 end
s3    7cb3016377add0bf  -3m2s   2024-07-07T12:45:42Z  2024-07-07T12:45:43Z

bin/rails litestream -- --database=storage/development.sqlite3

replica  generation        index  size    created
s3       7cb3016377add0bf  0      532584  2024-07-07T12:45:42Z
s3       87a822e9c2b78ddd  0      532554  2024-07-07T12:38:47Z
replica  generation        index  size    created
s3       7cb3016377add0bf  0      532584  2024-07-07T12:45:42Z
s3       87a822e9c2b78ddd  0      532554  2024-07-07T12:38:47Z

The restore command also works as follows:

bin/rails litestream:restore -- --database=storage/development.sqlite3 -o=storage/development-replica.sqlite3

However, the restored result is 0 in size as follows. What could be the issue?

ls -al storage | grep development

drwxr-xr-x@   4 me  staff      128  7  7 21:45 .development.sqlite3-litestream
-rw-r--r--@   1 me  staff        0  7  7 21:53 development-replica.sqlite3

-rw-r--r--@   1 me  staff    37112  7  7 21:42 development.sqlite3-wal

update)

If run the litestream directly, get normal results, as shown below:
