I wrote java code which connect to ElasticSearch node and save documents in index. I got below error: Exception in thread "Thread-21" java.lang.NoSuchFieldError: FAIL\_ON\_SYMBOL\_HASH\_OVERFLOW

I know this error is related to jackson version. My program uses below libraries: jackson-core-2.10.3.jar  
jackson-databind-2.8.11.6.jar  
jackson-dataformat-cbor-2.10.3.jar  
jackson-dataformat-smile-2.10.3.jar  
jackson-dataformat-yaml-2.10.3.jar

I use these versions according to below link: [https://www.elastic.co/guide/en/elasticsearch/reference/current/release-notes-7.7.0.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/release-notes-7.7.0.html)

Upgrade to Jackson 2.10.3 #53523 (issues: #27032, #45225)

Update jackson-databind to 2.8.11.6 #53522 (issue: #45225)

Could anyone help me?

Thanks
