I have installed Smile_Elasticsearch extension.It is working fine with the default mode but when I enabled developer mode it is showing an error.

Warning: call_user_func_array() expects parameter 1 to be a valid callback, first array member is not a valid class name or object in app/code/Smile/ElasticsuiteVirtualCategory/Model/Layer/Filter/Category.php on line 150

Please see attached screenshot.

enter image description here

Technology Detail's:

  • Magento version: 2.3
  • Smile Elasticsearch version: 2.7.0 (which is compatible with Magento 2.3)
  • Installed Elasticsearch version: 5.6.15 (which is compatible with magento 2.3)
  • PHP version: 7.1

So, Please let me know how can I fix this error? Your help would be appreciated. Thanks in advance.!!!
