Unexpected cbor code 0xa1 when decoding banyan::index::Index<trees::axtrees::AxTrees>.

[rkuhn]

This error basically says “I don’t want to read this dictionary of length 1”, which is the “kinded” representation of Index (DagCbor doesn’t like definite-length encoding, IIRC). I encountered this while developing event dump/restore functionality in Actyx. The restore part feeds events to BanyanStore::append0 (to preserve timestamps) and does not mess with the internals, so I don’t see how my code could influence the encoding of a Banyan index block.

How much work would it be to replace all DagCbor with cbor-data? I trust that implementation much more, it is very thoroughly tested to actually accept all valid CBOR.

Looking closer: 0xa1 is actually the hallmark of keyed encoding, while Index declares kinded … how could this possibly be mixed up?

I looked at the store in question (attached) with banyan-cli, added some debug printlns and found that the very first Index that is to be deserialized actually contains payload data.
