creating a nested json output file using jq variables using - shell

Question

I'm trying to create a json file via shellscript, and someone has mentioned jq, but I'm struggling a little bit to make it work:
The desire output is:
inboundurls{
"op": "add",
"path": "/support",
"apiSupports": [
{
"familyType": "EXAMPLE",
"healthCheckUris": "http://example.com"
}
],
"inboundurls": [
{
"healthCheckUris": "http://example.com"
}
]
}
Researching about I found a start point, but it's not working properly, I need some help, here is what I have:
script:
#!/bin/bash
apiSupports=$(jq -n --arg familyType EXAMPLE \
--arg healthCheckUris http://example.com \
'$ARGS.named'
)
final=$(jq -n --arg op "add" \
--arg path "/supportServices" \
--argjson apiSupports "[$apiSupports]" \
'$ARGS.named'
)
echo "$final"
the output of the script above:
{
"op": "add",
"path": "/supportServices",
"apiSupports": [
{
"familyType": "EXAMPLE",
"healthCheckUris": "http://example.com"
}
]
}
If anyone could help me I would be glad, or even suggesting Ideas, thank you in advance?

Answer 1

The following produces the valid JSON component of what is shown as the desired output:
jq -n --arg op "add" \
--arg path "/support" \
--arg familyType EXAMPLE \
--arg healthCheckUris http://example.com '
{$op, $path,
apiSupports: [ {$familyType, $healthCheckUris }],
inboundurls: [ {$healthCheckUris }]
}
'
