Thanks @dadoonet
I saw the plugin document and installed it but I could not understand how the file should be provided in that API
In document it is shown as
PUT my_index/my_type/my_id?pipeline=attachment
{
"data": "e1xydGYxXGFuc2kNCkxvcmVtIGlwc3VtIGRvbG9yIHNpdCBhbWV0DQpccGFyIH0="
}
Ho can I specify my file? Do I need to specify file path somewhere?
