no such index [index: ] when trying to scroll with elasticsearch - php

Question

Since I moved from 2.4 to 5.6, I have an error when using a scroll query :
$query = '{
"scroll" : "1m",
"scroll_id" : "'. $scrollId .'"
}';
$path = '/_search/scroll';
$responseArray = $this->sendQuery($index, $path, Request::GET, $query);
error :
CRITICAL - Uncaught PHP Exception Elastica\Exception\ResponseException: "no such index [index: ]" at /code/vendor/ruflin/elastica/lib/Elastica/Transport/Http.php line 179
Here the initial query I'm using :
$path = 'dataIndex/_search?scroll=1m';
$query = sprintf(
'{
"size" : 500,
"stored_fields": "_source"
}'
);
And how I call my scroll function
$hits = $this->getElasticNextScroll($this->dataIndex, $hits['_scroll_id']);
One of the solution I tried was to send the request with POST but I got another error :
CRITICAL - Uncaught PHP Exception Elastica\Exception\ResponseException: "String index out of range: 0" at /code/vendor/ruflin/elastica/lib/Elastica/Transport/Http.php line 179
EDIT SOLUTION :
the path '/_search/scroll' worked in 2.4 but doesn't work anymore in 5.3. You need to remove the first / : '_search/scroll'

Answer 1

specify what value is passed to $index and what is included in the Request :: GET function

Answer 2

Index {#9208
-originalName: null
-typeCache: []
#_name: "index_data"
#_client: Client {#9234
-indexCache: array:1 [
"index_data" => Index {#9208}
]
-stopwatch: Stopwatch {#157
...
And here the stack error I have :
