Using sub queries to create JSON file - json

Question

I'm trying to create a JSON file for a new project that I'm currently looking into I've got most of it working as expected but I'm now at a point where I'm trying to use sub queries in order to format the JSON correctly.
I've tried to use the following sub query but SQL doesn't like the formatting.
` SELECT
'Admin User TEST ONLY PLEASE IGNORE' AS AdditionalNotes
(
SELECT v.atFault
FROM dbo.ic_DP_AX ax
CROSS APPLY (VALUES (ax.Acc_fault1), (ax.Acc_fault2)) v (atFault)
FOR JSON AUTO
) AS InsuredPartyClaims,
(
SELECT Acc_fault3 AS atFault
FROM dbo.ic_DP_AX
FOR JSON AUTO
) AS InsuredPartyConvictions
FOR JSON PATH) ROOT('InsuredParties')
FROM
dbo.icp_Daprospect AS p INNER JOIN
dbo.icp_Dapolicy AS d ON p.Branch# = d.Branch# AND p.ClientRef# =
d.ClientRef# LEFT OUTER JOIN
dbo.ic_DP_AX AS ax ON P.Branch# = ax.B# AND ax.PolRef# = d.PolicyRef#
LEFT OUTER JOIN
WHERE
d.PolicyRef# = '' AND
d.Branch# = 0`
FOR JSON PATH
The output I'm trying to achieve is:
"InsuredParties": [
{
"InsuredPartyClaims": [
{
"atFault": false
},
{
"atFault": true
}
],
"InsuredPartyConvictions": [
{
"atFault": false
},
Can anyone see what I'm doing wrong? I'm trying to keep this as simple as possible.

It's always difficult without sample data, but the foolowing example is a possible solution:
Table:
CREATE TABLE dbo.ic_DP_AX (Acc_fault1 bit, Acc_fault2 bit, Acc_fault3 bit)
INSERT INTO dbo.ic_DP_AX (Acc_fault1, Acc_fault2, Acc_fault3)
VALUES (0, 1, 0)
Statment:
SELECT
(
SELECT v.atFault
FROM dbo.ic_DP_AX ax
CROSS APPLY (VALUES (ax.Acc_fault1), (ax.Acc_fault2)) v (atFault)
FOR JSON AUTO
) AS InsuredPartyClaims,
(
SELECT Acc_fault3 AS atFault
FROM dbo.ic_DP_AX
FOR JSON AUTO
) AS InsuredPartyConvictions
FOR JSON PATH, ROOT('InsuredParties')
Result:
{
"InsuredParties":[
{
"InsuredPartyClaims":[
{
"atFault":false
},
{
"atFault":true
}
],
"InsuredPartyConvictions":[
{
"atFault":false
}
]
}
]
}

The subqueries need to return JSON as well.
Try
(
(SELECT ax.Acc_fault1 AS [atFault] FROM dbo.ic_DP_AX AS ax FOR JSON PATH) AS [PartyClaims]
(SELECT ax.Acc_fault2 AS [atFault] FROM dbo.ic_DP_AX AS ax FOR JSON PATH) AS [PartyClaims]
(SELECT ax.Acc_fault3 AS [atFault] FROM dbo.ic_DP_AX AS ax FOR JSON PATH) AS [PartyConvictions]
) FOR JSON PATH AS [InsuredParties]
