Error handling: errors don't show variable name

[folex]

For example, in this error, it's impossible to say which array is empty, records-fix or records-fix[0].relay_id.

    {
      "instruction": "call records-fix.$.[0].relay_id.[0] (\"peer\" \"timestamp_ms\") [] host_peer_time",
      "msg": "value '[]' does not contain element for idx = '0'",
      "peer_id": "12D3KooWD32M26ob1aNvqMUicpUH8D7SLjwz1W4GNjs8uYtJUdqS",
    }

For AIR lambdas, it would be great to show name of the variable that caused the error.
