Powershell ConvertFrom-Json eats node - json

Question

ConvertFrom-Json is failing to successfully parse my Json into object, despite my object being legal Json.
I'm using the latest version of Powershell.
When I try parsing a google request JSON body like this:
{
"reportScope": {
"agencyId": "11111111111111111",
"advertiserId": "22222222222222222"
},
"reportType": "adGroup",
"columns": [
{
"columnName": "status"
},
{
"columnName": "date"
},
{
"columnName": "account"
},
{
"columnName": "accountType"
},
{
"columnName": "campaign"
},
{
"columnName": "adGroup"
},
{
"columnName": "deviceSegment"
},
{
"columnName": "impr"
},
{
"columnName": "clicks"
},
{
"columnName": "dfaRevenue"
},
{
"columnName": "cost"
},
{
"columnName": "avgPos"
}
],
"timeRange": {
"startDate": "2017-09-13",
"endDate": "2017-08-14"
},
"filters": [
{
"column": {"columnName": "impr"},
"operator": "greaterThan",
"values": "0"
}
],
"downloadFormat": "csv",
"maxRowsPerFile": 6000000,
"statisticsCurrency": "agency",
"verifySingleTimeZone": "false",
"includeRemovedEntities": "false"
}
I get an object like this:
[DBG]: PS Microsoft.PowerShell.Core\FileSystem::\\psDashboard>> $objJson
reportScope : #{agencyId=11111111111111111; advertiserId=22222222222222222}
reportType : adGroup
columns : {#{columnName=status}, #{columnName=date}, #{columnName=account}, #{columnName=accountType}...}
timeRange : #{startDate=2017-09-13; endDate=2017-08-14}
filters : {#{column=; operator=greaterThan; values=0}}
downloadFormat : csv
maxRowsPerFile : 6000000
statisticsCurrency : agency
verifySingleTimeZone : false
includeRemovedEntities : false
[DBG]: PS Microsoft.PowerShell.Core\FileSystem::\\psDashboard>> $objJson.filters
column operator values
------ -------- ------
greaterThan 0
Notice column should contain #{columnNane=imgr} but it instead contains nothing.
Code used for parsing:
$objJson = Get-Content -Path $FileName -Raw | ConvertFrom-Json
Any ideas?

i took your code and was able to get to the object you are looking for I first put it in a Here string #""# and was able to get to it.. then like you I put it in a variable and piped to convertfrom-json and got the ame results.
$test = #"
{
"reportScope": {
"agencyId": "11111111111111111",
"advertiserId": "22222222222222222"
},
"reportType": "adGroup",
"columns": [
{
"columnName": "status"
},
{
"columnName": "date"
},
{
"columnName": "account"
},
{
"columnName": "accountType"
},
{
"columnName": "campaign"
},
{
"columnName": "adGroup"
},
{
"columnName": "deviceSegment"
},
{
"columnName": "impr"
},
{
"columnName": "clicks"
},
{
"columnName": "dfaRevenue"
},
{
"columnName": "cost"
},
{
"columnName": "avgPos"
}
],
"timeRange": {
"startDate": "2017-09-13",
"endDate": "2017-08-14"
},
"filters": [
{
"column": {"columnName": "impr"},
"operator": "greaterThan",
"values": "0"
}
],
"downloadFormat": "csv",
"maxRowsPerFile": 6000000,
"statisticsCurrency": "agency",
"verifySingleTimeZone": "false",
"includeRemovedEntities": "false"
}
"#
$t = $test | ConvertFrom-Json
$t.filters.column
PS C:\WINDOWS\system32> $t.filters
column operator values
------ -------- ------
#{columnName=impr} greaterThan 0
PS C:\WINDOWS\system32> $t.filters.column
columnName
----------
impr
Using get content and using convertfrom-json.
PS C:\WINDOWS\system32> $test.filters
column operator values
------ -------- ------
#{columnName=impr} greaterThan 0
PS C:\WINDOWS\system32> $test.filters.column
columnName
----------
impr
could it be your version of convertFrom-json my module version is:
PS C:\WINDOWS\system32> gcm convertfrom-json
CommandType Name Version Source
----------- ---- ------- ------
Cmdlet ConvertFrom-Json 3.1.0.0 Microsoft.PowerShell.Utility
