Access the error message

[howdu]

I had to edit the core code to find the error message. It was returning the general error: Request provided was invalid.

Json response was obvious how to fix once I could see the error.
[
"destination_addresses" => []
"error_message" => "departure_time is in the past. Traffic information is only available for future and current times."
"origin_addresses" => []
"rows" => []
"status" => "INVALID_REQUEST"
]

Thanks, i had an RESPONSE_REQUEST_DENIED status and ended being "API keys with referer restrictions cannot be used with this API."
