Internal server error on eth_callBundle method with Flashbot's Sepolia RPC

[pashkin-acc]

https://relay-sepolia.flashbots.net returns 500 Internal Server Error on eth_callBundle method call:

{
  "error": "Internal Server Error"
}

Though, for example, eth_sendBundle method works.

exactly same issue here! I think it doesn't work properly on sepolia, since my eth_sendBundle methods get timeout results or not inclueded always. Any update?

issue still persists both on bundle simulation and when sending bundle:

reason: 'bad response',
code: 'SERVER_ERROR',
status: 500,
body: '{"error":"Internal Server Error"}',
requestBody: '{"method":"eth_callBundle","params":[{"txs": .... }] }'
