I am using cURL inside bash to fetch json data from remote API. The response looks like this:

[
  {
        "services": [
            "HOM"
        ],
        "specialServiceId": "APPOINTMENT",
        "brandedName": "Appointment Home Delivery®",
        "incompatibleSpecialServices": [
            "DATE",
            "EVENING"
        ],
        "inputParameterRules": [
            {
                "name": "PHONE_NUMBER",
                "brandedName": "Appointment Phone Number",
                "required": true,
                "format":"^d{10,15}$",
                "description": "A valid 10 to 15 digit phone number including area code and optional extension"
            }
        ]
    },
    {
        "services": [
            "NDA_AM_EH",
            "2DA",
        ],
        "specialServiceId": "NO_SIG",
        "brandedName": "No Signature Required",
        "categoryId": "DEL_CON",
        "incompatibleSpecialServices": [
            "SIG",
            "DIRECT_SIG",
        ],
        "inputParameterRules": [
            {
                "name": "SIGNATURE_RELEASE_NUMBER",
                "description": "A valid signature release number"
            }
        ],
        "specialServiceLevel": "ALLPKG"
    },
  {...},
  {...}
] 

As you can see the format field inside inputParameterRules for PHONE_NUMBER contains a single backslash which makes this JSON un-parseable.

I would like to

1. Either replace the single backslash with a double backslash before storing this json in a file OR
2. Delete the format field.

Thanks

Tried something like this:
SPECIAL_SERVICES_RESPONSE=$(curl -s -X GET -H “Authorization: Bearer ${BEARER_TOKEN}” “${SPECIAL_SERVICES_URL}” | jq ‘[.[].inputParameterRules[] | del(.format)]’)

But it produces no results
