Unable to use chainHead_v1_call on "Parallel" parachain

[josepot]

When trying to use smoldot against the Parallel parachain, it seems like all the operation requests "fail" with an operationInaccessible event, and after trying a bit later we get the same result over and over.

These are the logs:

• Smoldot low-level logs (I just edited the comment to update these logs, the ones before were not readable)
• Logs of the JSON-RPC messages

The chainSpec for this parachain is:

  }
}

What happens is that the full nodes that we ask a Merkle proof from indicate that they're unable to answer the request (basically an error on their side).
There's nothing indicating to smoldot what problem could have happened, so the way forward is to look at what the full node logs say.
