I am getting this exception after a while when i try to append JSON document under same ID in the Elasticsearch index

How my data is getting appended.

Index\_name  
id : 1234  
JSON{}  
JSON{}  
.  
.  
JSON{}

My code snippet:  
es.update(index=NEW\_INDEX, id=source\_id, body={"script": {  
"lang": "painless",  
"inline": "ctx.\_source.{}.CNT += params.CNT".format(StudentID),  
"params": {  
"CNT": 1  
}  
}})

My exception :

Traceback (most recent call last):  
File "consumer.py", line 139, in   
"uuid": packet\_dict  
File "/home/machine/Desktop/PyDir/lib/python3.6/site-packages/elasticsearch/client/utils.py", line 84, in \_wrapped

Code seems to work for sometime then produces the above exception.

do you have a full exception?

You can also add parameters to get a full exception. See [https://www.elastic.co/guide/en/elasticsearch/reference/7.1/common-options.html#common-options-error-options](https://www.elastic.co/guide/en/elasticsearch/reference/7.1/common-options.html#common-options-error-options)

Also, a fully fledged example using curl or the console tools syntax would help a lot, as this would allow far more people to reproduce it.

Thank you!

I have found the actual issue in Elastic search log. It's total fields limit in index has exceeded 1000.  
Is there a way to update my index with new limit ? I am currently using elastic search python api

And you guys set the limit for a reason. I would like know the reason behind it. Thanks
