Submitting a meta transaction without an API key header gives partial tx with hexadecimal numbers

[kimpers]

Submitting a meta transaction to meta_transaction/v0/submit without providing an 0x-api-key header returns a partial transaction with hexadecimal numbers for gas, gasPrice, value

Expected Behavior

POST /meta_transaction/v0/submit

{
  "code": 106,
  "ethereumTransaction": {
    "data": "0xdeadbeef",
    "gas": "265080",
    "gasPrice": "35000000000",
    "to": "0x....",
    "value": "10500000000000000"
  },
  "reason": "Unable to submit transaction on behalf of taker"
}

Current Behavior

POST /meta_transaction/v0/submit

{
  "code": 106,
  "ethereumTransaction": {
    "data": "0xdeadbeef",
    "gas": "0x40b78",
    "gasPrice": "0x826299e00",
    "to": "0x....",
    "value": "0x254db1c2244000"
  },
  "reason": "Unable to submit transaction on behalf of taker"
}
