While testing the logs, I see some \ escaping and I don't think they're needed, right?

validator-1  | time=2024-03-15T11:08:45.413Z level=INFO msg="INFO dispatcher::machine::rollups_broker: producing input event event=RollupsInput { parent_id: \"0\", epoch_index: 0, inputs_sent_count: 1, data: AdvanceStateInput(RollupsAdvanceStateInput { metadata: InputMetadata { msg_sender: f39fd6e51aad88f6f4ce6ab8827279cfffb92266, block_number: 13, timestamp: 1710500920, epoch_index: 0, input_index: 0 }, payload: 3q2+7w==, tx_hash: 71932220268ade67936c208a119841cf9ef5b8b3b36ab380740fd814401baf2f }) }" service=dispatcher

This when sending an input:

validator-1  | time=2024-03-15T11:08:45.426Z level=INFO msg="\x1b[0m\x1b[38;5;8m[\x1b[0m\x1b[0m\x1b[32mINFO \x1b[0m rollup_http_server::http_service\x1b[0m\x1b[38;5;8m]\x1b[0m Received new request of type ADVANCE" service=server-manager

@endersonmaia they are added automatically because they are already inside another string. msg="INFO...

@endersonmaia they are added automatically because they are already inside another string. msg="INFO...

Yeah, they're useless and are extra bytes in the log stream. Is it hard to avoid/remove them?

And what about the second example?

msg="\x1b[0m\x1b[38;5;8m[\x1b[0m\x1b[0m\x1b[32mINFO \x1b[0m

Looks like terminal coloring from the inner rust service logs.

Oh boy, this is looking neat! I loved how text/template made things so much easier to understand. I've only left a request concerning the logs and other small things.
