JQ Error: Cannot iterate over string while trying to map IP and Ports - json

Question

I have a below json output, I would love to remove duplicate data and map the data in a table format using jq. I am using the below query but I keep getting an error;
Cannot iterate over string ("78.45.196...)
e.t.c.
Json data
[
{
"ip": "78.45.196.23",
"timestamp": "1616566245",
"ports": [
{
"port": 5060,
"proto": "tcp",
"status": "open",
"reason": "syn-ack",
"ttl": 50
}
]
},
{
"ip": "67.89.378.82",
"timestamp": "1616566255",
"ports": [
{
"port": 2000,
"proto": "tcp",
"status": "open",
"reason": "syn-ack",
"ttl": 50
}
]
},
{
"ip": "67.89.378.82",
"timestamp": "1616566255",
"ports": [
{
"port": 2080,
"proto": "tcp",
"status": "open",
"reason": "syn-ack",
"ttl": 50
}
]
},
{
"ip": "78.45.196.23",
"timestamp": "1616566245",
"ports": [
{
"port": 5060,
"proto": "tcp",
"status": "open",
"reason": "syn-ack",
"ttl": 50
}
]
},
{
"ip": "67.89.378.82",
"timestamp": "1616566255",
"ports": [
{
"port": 2000,
"proto": "tcp",
"status": "open",
"reason": "syn-ack",
"ttl": 50
}
]
},
{
"ip": "78.45.196.23",
"timestamp": "1616566245",
"ports": [
{
"port": 5080,
"proto": "tcp",
"status": "open",
"reason": "syn-ack",
"ttl": 50
}
]
}
]
My query
jq -r '.[][] | group_by(.ip) | map({ip: .ip, ports: map(.ports[].port) | add | unique})' jsonfile.json
Expected output
To remove duplicates and get ip and ports.
Or can one explain to me how to get unique values from both IP and ports.
[
{"ip:" "67.89.378.82", "ports:"[2000, 2080]},
{"ip:" "78.45.196.23", "ports:"[5060, 5080]}
]

Answer 1

Construct your desired JSON immediately following the group_by()
group_by(.ip) |
map
(
{
ip: .[0].ip,
ports: [ .[].ports[].port ] | unique
}
)
jq play link
Follow-up question to discard IPs that have only port as 0
group_by(.ip) |
map
(
{
ip: .[0].ip,
ports: [ .[].ports[] | select(.port != 0 ).port ] | unique
} |
select(.ports | length > 0)
)
