Can't see variable contents in inspect/network

Hi

I've a button that is activated by Vuejs to place an order on my system, when i click the button, it calls the Vuejs routine, passes the variables to the php routine to store that information via an axios push call, which is working fine.

When I then open the inspect panel, click on Place order, my routine crashes, when I then click on the preview, all I see is:-

array:1 [
  "e" => Illuminate\Database\QueryException {#1119}
]

For some reason, I can't seen any of the information, before last week, I definitely could, so am wondering if either I've changed something (no idea what) or something has changed elsewhere!

If I now put a dd in my code, I can see:-

array:31 [
  "request" => Illuminate\Http\Request {#43}
  "branch" => {#1099}
  "response" => []
  "landmark_api" => ""
  "landmark_account_id" => ""
  "landmark_client_id" => ""
  "landmark_client_secret" => ""
  "contact_id" => "9225f2fc-a192-4ccb-af83-2a7342535e9f"
  "main_contact" => {#861}
  "contacts" => array:2 []
  "ch" => Closed resource @11

I thought that I should be able t see the sub variables within those like 'contacts' as it's an array of 2 items. request should also allow me to view the sub variables of that!!

Does anybody know what I've done and now to resolve it?

Regards Carl.
