    Error: Failed to snapshot the working copy
    Caused by: New file $TEST_ENV/repo/large of size ~13.0B exceeds snapshot.max-new-file-size (10.0B)
    Hint: Increase the value of the `snapshot.max-new-file-size` config option if you
    want this file to be snapshotted. Otherwise add it to your `.gitignore` file.
