Hi all,

I got an exception while trying to use a script aggregation in Kibana using the json input:

 ![image](https://us1.discourse-cdn.com/elastic/original/3X/8/d/8d51e5f6edcb983c170df22f3e852221c6ad0459.png)

I can reproduce the error in Dev Tools when I specify both the field and the script for the same aggregation:

> GET online/\_search?size=0  
> {  
> "aggs": {  
> "tag": {  
> "terms": {  
> "field": "tag.keyword",  
> "script": {  
> "source": "doc['tag.keyword']",  
> "lang": "painless"  
> }  
> }  
> }  
> }  
> }

If I remove the field attribute, everything is working perfectly:

> GET online/\_search?size=0  
> {  
> "aggs": {  
> "tag": {  
> "terms": {  
> "script": {  
> "source": "doc['tag.keyword']",  
> "lang": "painless"  
> }  
> }  
> }  
> }  
> }

But Kibana does not allow me to use JSON input without specifying a field in aggregation.

I am using version 5.6.7.

Thank you for you help,

Aurelien

I installed locally last version of ES and Kibana (7.2) and it is working as expected on this version. So I think best way to solve my issue is to upgrade...
