Creating a pscustomobject from an array returns whole array

I'm trying to create a JSON file in PS that contains some values that i have stored in some arrays.

$array = [PSCustomObject]@{
  EnvironmentVariables = @()
  ConnectionReferences = @(
    foreach($i in $connectors){
       [PSCustomObject]@{
        LogicalName = $LogicalName
        ConnectionId = $connectors.ConnectorName
        ConnectorId = $ConnectorId
      }
    }    
  )
} | ConvertTo-Json -Depth 3

that returns the whole array for each variable. If i put [0] it takes the first value in the array and prints it. But i want it to continue to create objects for each value in these arrays. And if it's possible i would like to match some values. For example, "If $connectorId contains value from $connectors.ConnectionName" i want that to be a custom object.

This may be an easy fix, but i'm quite new to Powershell...
