How to update json with variable array using bash script

I have a json file test.json with below format:

{  "environments":             {"egress": [                ]            }}

I want to add objects under egress field with multiple variable values. I have written a bash script test.sh with below code snippet:

egress_port='[80,443]'egress_value='[test,test1]'egress_protocol='[http,https]'# IFS=','echo $egress_portecho $egress_valueecho $egress_protocolcat test.json |jq  --argjson port "$egress_port" \   --argjson value "$egress_value" \   --argjson protocol "$egress_protocol" \'.environments.egress = ([$port, $value, $protocol] | transpose |   map ({port: .[0], type: "external", value: .[1], protocol: .[2]}))'

I want json to be updated in below format:

{  "environments":             {"egress": [                   {"port": "80", "type": "external", "value": "test", "protocol": "http"                   },                   {"port": "443", "type": "external", "value": "test1", "protocol": "https"                   }                ]            }}

When i run it, it throws an error:

jq: invalid JSON text passed to --argjson

Can someone help me here?
