unable to add value on nested property - json

Question

I am struggling to modify the data of properties that are deeply nested in my PSObject. If I try to modify the values Powershell just throws the exception of saying that it cannot find the value, but if I just call upon the value itself it can be found without an issue.
The raw data of the json object looks like this:
[
{
"#CREATED": "2017-05-04 08:36:23",
"#LAST_MODIFIED": "2017-05-08 08:18:58",

"FIRST_NAME": {
"#FIELD_ID": 2,
"#LAST_MODIFIED": "2017-05-04 08:36:24",
"#VALID_FROM": "2017-05-04",
"value": "Example"
},
"LAST_NAME": {
"#FIELD_ID": 3,

"#VALID_FROM": "2017-05-04",

"#LAST_MODIFIED": "2017-05-04 14:26:55",
"#VALID_FROM": "2017-05-04",
"value": "Stockholm"
}
},
"CUSTOM_FIELDS": {
"FIELD": [
{
"#FIELD_ID": 1033,
"#MODE": 0,
"#LAST_MODIFIED": "2017-05-24 10:15:24",
"#VALID_FROM": "2017-05-24",
"NAME": "Department",
"VALUE": {
"value": "Example Department"
}
},
{
"#FIELD_ID": 1034,
"#MODE": 0,
"#LAST_MODIFIED": "2017-05-04 08:36:24",
"#VALID_FROM": "2017-05-04",
"NAME": "VPN",
"VALUE": {
"value": "Yes"
}
},
{
"#FIELD_ID": 1036,
"#LAST_MODIFIED": "2017-05-04 08:36:24",
"#VALID_FROM": "2017-05-04",
"NAME": "Titel",
"VALUE": {
"value": "Test-User"
}
},
{
"#FIELD_ID": 1022,
"#MODE": 0,
"#LAST_MODIFIED": "2017-05-04 16:43:18",
"#VALID_FROM": "2017-05-04",
"NAME": "Authorizations",
"VALUES": {
"VALUE": [
{
"value": "Auth 1"
},
{
"value": "Auth 2"
},
{
"value": "Auth 3"
},
{
"value": "Auth 4"
}
]
}
}
]
}
}
]
My current code:
$users = get-content "C:\Working-Branch\Temp\NotFoundUsers - Copy.txt"| ConvertFrom-Json
foreach($user in $users){
$user.CUSTOM_FIELDS.FIELD.values.Value.value
$NewValue = $user.CUSTOM_FIELDS.FIELD.values.Value.value
$NewValue += "Test"
$NewValue
$($user.CUSTOM_FIELDS.FIELD.values.Value).value = $newValue
}
Which results in the following output:
Auth 1
Auth 2
Auth 3
Auth 4
Auth 1
Auth 2
Auth 3
Auth 4
Test
The property 'value' cannot be found on this object. Verify that the property exists and can be set.
At line:10 char:5
+ $($user.CUSTOM_FIELDS.FIELD.values.Value).value = $newValue
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo : InvalidOperation: (:) [], RuntimeException
+ FullyQualifiedErrorId : PropertyAssignmentException
So I know the property exists because I call upon it two times, one directly on the Object and one time after I have added the value "test" to it. But when I try to update the Orignal object it says it can not find the value "Value" on the object.
I tried following the what was suggested in This post, but it still fails for me. I both with the "+=" operator and the "=" operator. Same error with both of them.
Result of Get-member

I think you need to find the field with the member Values
$newvalue =#{
"value" = "Test"
}
foreach($user in $users){
$array = $user.CUSTOM_FIELDS.FIELD.values.value
$array += $newvalue
foreach ($field in $user.CUSTOM_FIELDS.FIELD)
{
if ($field.values -ne $null)
{
$field.values.value = $array
}
}
$user.CUSTOM_FIELDS.FIELD.values.Value
}
Then output for $user.CUSTOM_FIELDS.FIELD.values.Value is
value
