This is how I created the index through postman.
in the $result variable im sending
(
[last_consult_by] => xxxxxx
[mpi] => xxxxxxxx
[bill_id] => 176073
[bill_date] => 2018-07-12 12:00:00
[site] => xxx
[effective_edd] => 2018-07-28 12:00:00
[is_converted] => 0
[admitting_physician] => xxxxxxxxx
[days] => 16
[trim] => Array
(
[trim3] => 1
)
)
$params = [
'index' => 'patient_trimester',
'type' => 'patient_trimester',
'body' => $result
];
$res = $client->index($params);
print_r($res); exit;
I'm not getting why mapper_parsing_exception is happening.
Is this because of my mapping of datatypes? mapping given for Datatype of effective_edd,bill_date and the trim is right ?
please help me out to resolve this issue.
