bafybeidu5wtgjfakk6q7uyykhf2225bko4wlgrug5m6x3pabtanopolsg4 appears to lead to a black hole. Returns a CAR with it listed as the root but no body.

curl -v -H 'Accept: application/vnd.ipld.car;version=1;order=dfs;dups=y' 'https://dag.w3s.link:443/ipfs/bafybeidu5wtgjfakk6q7uyykhf2225bko4wlgrug5m6x3pabtanopolsg4?dag-scope=block' -o w3s.car

Lots of failing requests trying to path from this block:

Known issue - this is a CAR that hasn't been moved into Cloudflare R2 just yet.

Same issue with bafybeihkbmy5eajjtg42b4auzxcpheksf5pt5bojnm4zr4ba36jwwtfbmi? Lots of paths such as /9816.json, /9225.json, /8337.json. I can curl with just the CID and get the root block, a unixfs shard, but dag-scope of entity or all doesn't get me anything more than the root.

Not sure if this is helpful but here's some more:

I've confirmed at least QmVFh1a8w6t7gUgJkwuV4jZfdmf73FHtNcQgAsDkwpQGa6/231399.json resolves properly via bitswap, so at least one of the paths above is valid but unfetchable.
