Solana accounts can be up to 10 MB. With base64/hex encoding overhead, the JSON-RPC payload for a max-size account reaches ~13.5 MB, exceeding the default 5 MiB limit and causing HTTP 413 during surfnet_setAccount runbook execution. 15 MiB accommodates the largest possible account with headroom.

Summary
jsonrpc_http_servermax_request_body_sizefrom the default 5 MiB to 15 MiBProblem
Solana accounts can be up to 10 MB. When the txtx runbook engine executes
set_accountdirectives viasurfnet_setAccountJSON-RPC calls (self-loopback to the HTTP server), large accounts — such as circuit buffer accounts — get hex/base64-encoded in the JSON-RPC envelope, reaching ~13.5 MB. This exceeds the default 5 MiB limit, causing HTTP 413 responses.Fix
One-line change:
.max_request_body_size(15 * 1024 * 1024)on theServerBuilder. 15 MiB accommodates the largest possible Solana account with encoding overhead and headroom.
