panic: runtime error: invalid memory address or nil pointer dereference

[SpontaneousOverthrow]

Vouch Version: 1.6.1

Sometimes in logs I see:

[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0xd33d6d]

It started after I added MeV. I have two instances of vouch connected to the three dirks with about 2000 keys. Here example of blockrelay config:

{
  "default_config": {
    "builder": {
      "enabled": true,
      "relays": [
        "https://0xafa4c6985aa049fb79dd37010438cfebeb0f2bd42b115b89dd678dab0670c1de38da0c4e9138c9290a398ecd9a0b3110@boost-relay-goerli.flashbots.net/",

      ]
    },
    "fee_recipient": "0xccc...bbbb"
  },
  "proposer_config": {

      },

        ]
      },
      "fee_recipient": "0xaaa...bbbb"
    }
   }
 }

In proposer_config I have rewrites for all 2000 keys.

This issue has been fixed in 64cd0c01 and will be made available in Vouch 1.6.2, which is expected to be released in the next few days.

[SpontaneousOverthrow]

am I correct that this issue related to changing fee recipient address?

Vouch 1.6.2 has been released.
