Hi Team,

I am not able to generate CSV report from Kibana.

Getting error:  
**Couldn't create report for search**  
**TypeError: FieldFormat is not a constructor**

![Kibana-error](https://us1.discourse-cdn.com/elastic/original/3X/9/c/9c071b231f6192e40fb3db9ee4a9943f1fa20d28.jpeg)

I am able to download CSV report for old saved object.

Thanks

Hey @Aniket_Salvi ,

That looks like a bug to me unless you're using some old Kibana version? If you still see this error in Kibana 7.11.0, then would you mind filing a bug with the steps to reproduce here: [https://github.com/elastic/kibana/issues/new?assignees=&labels=bug&template=Bug\_report.md](https://github.com/elastic/kibana/issues/new?assignees=&labels=bug&template=Bug_report.md)

Thanks,  
Oleg

Hi @azasypkin ,

Yes, I am using the older version of kibana.

Elasticsearch version - 6.4.3  
Kibana version - 6.4.3

How can I handle these issues in the older version?

Thanks
