What's your CLI version?

0.84.2

Description & steps to reproduce

The following agent config results in parsing error when running through Kurtosis, but works when input directly into the agent image:

   "base":{
      "name":"base",
      "chainId":84531,
      "domainId":84531,
      "protocol":"ethereum",
      "rpcUrls":[
         {
            "http":"https://goerli.base.org"
         }
      ],
      "mailbox":"<>",
      "interchainGasPaymaster":"<>",
      "validatorAnnounce":"<>",
      "index":{
         "from":10670130
      }
   },
   "goerli":{
      "chainId":5,
      "domainId":5,
      "name":"goerli",
      "protocol":"ethereum",
      "displayName":"Goerli",
      "nativeToken":{
         "name":"Ether",
         "symbol":"ETH",
         "decimals":18
      },
      "rpcUrls":[
         {
            "http":"https://goerli.infura.io/v3/9aa3d95b3bc440fa88ea12eaa4456161"
         },
         {
            "http":"https://rpc.ankr.com/eth_goerli"
         },
         {
            "http":"https://eth-goerli.public.blastapi.io"
         }
      ],
      "blockExplorers":[
         {

            "url":"https://goerli.etherscan.io",
            "apiUrl":"https://api-goerli.etherscan.io/api",
            "family":"etherscan"
         }
      ],
      "blocks":{
         "confirmations":1,
         "reorgPeriod":2,
         "estimateBlockTime":13
      },
      "isTestnet":True,
      "mailbox":"<>",
      "interchainGasPaymaster":"<>",
      "validatorAnnounce":"<>",
      "index":{
         "from":8039005
      }
   },
   "chains":{
      "base":{
         "name":"base",
         "domain":84531,
         "addresses":{
            "mailbox":"<>",
            "interchainGasPaymaster":"<>",
            "validatorAnnounce":"<>"
         },
         "protocol":"ethereum",
         "finalityBlocks":1,
         "index":{
            "from":10670130
         }
      },
      "goerli":{
         "name":"goerli",
         "domain":5,
         "addresses":{
            "mailbox":"<>",
            "interchainGasPaymaster":"<>",
            "validatorAnnounce":"<>"
         },
         "protocol":"ethereum",
         "finalityBlocks":2,
         "index":{
            "from":8039005
         }
      }
   }
}```

### Desired behavior

The schema should be parsable by the `relayer` and `validator`.

### What is the severity of this bug?

Critical; I am blocked and Kurtosis is unusable for me because of this bug.

### What area of the product does this pertain to?

Frontend: the Graphical User Interface, including the Enclave Manager
