RPC error message is being swallowed
When calling something like AsyncClient::broadcast
, if we get an RPC error back from the electrum server, we immediately convert the response into a generic one based on the status. This means that we lose the context of the error message, which makes debugging harder as one has to check the logs of the electrum server to figure out exactly what went wrong.
For instance, electrum might report
WARN - HttpError(400, "sendrawtransaction RPC error: {\"code\":-26,\"message\":\"non-mandatory-script-verify-flag (Signature must be zero for failed CHECK(MULTI)SIG operation)\"}")
whilst the client gives us
Esplora client error: Reqwest(reqwest::Error { kind: Status(400), url: Url { scheme: "http", cannot_be_a_base: false, username: "", password: None, host: Some(Domain("localhost")), port: Some(3000), path: "/tx", query: None, fragment: None } })
which is much less useful.
