Tracing the data flow from Channel::new_outbound:

lightning/src/ln/channel.rs:917 &user_id = 1
lightning/src/ln/channel.rs:917 &channel_keys_id = [ 0, 0, 0, 0, 158, 219, 132, 97, 69, 212, 64, 34, 221, 63, 215, 231, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, ]

In keysinterface.rs:
ightning/src/chain/keysinterface.rs:1047 params = [ 0, 0, 0, 0, 158, 219, 132, 97, 69, 212, 64, 34, 221, 63, 215, 231, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1, ]
lightning/src/chain/keysinterface.rs:1047 &chan_id = 2665186401

Which is not in the range of [0, 2^31 - 1], returning InvalidChildNumber(2665186401), which LDK .expect()s on with the "key space exhausted" message.
