[Koha] French (fr-FR) Translator problem

[amandeep.kapila at aol.in]

Dear all,
I am adding some language to my Koha OPAC and Staff Client. I can add the languages, as desired, with koha-translate package service but unfortunately its not working as expected for French (fr-FR). When I enable French on either of the interfaces the search results display no bibliographic/metadata for the records, only blank spaces, although it returns exact number of results. 
I have tried with both Zebra and Elasticsearch, same result. For other languages (Spanish, Arabic etc.) everything shows OK. Even the Canadian version of French (fr-CA) is also working. Its happening both in OPAC and Staff Client. 
The plack opac error logs display message like below,
