Hello,

I have an issue when i try to load the data from elasticsearch REST API with the scan scroll method (QlikSense June 2017 Patch 1 - 11.11.2)

  2017-08-22 18:23:36      Error: QVX_UNEXPECTED_END_OF_DATA: Connection with server closed prematurely.

  2017-08-22 18:23:36      Execution Failed

  2017-08-22 18:23:36      Execution finished.

Note : This error is raised only when I try to retrieve data from a large index with multiple columns (>60) and thousands of lines.

Please let me know how can i fix this error ?
