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

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

指定将什么值传递给$ index以及什么包含在Request :: GET函数中

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 :
