Error: parse error: invalid character read: value limit exceeded reading newly created hybrid torrent

[htnyquist]

I used torrenttools to create a hybrid torrent on about 1TiB of data. The resulting file is about 20MB and can't be opened by qBittorrent ("the v1 and v2 metadata does not match"), but actually even torrenttools info out.torrent fails with an exception:

The exception message is Error: parse error: invalid character read at position 9302219: value limit exceeded.
Here is the (lightly redacted) start of the log, during the torrent creation:

I can provide the 20MB output torrent privately if necessary.
