It would help if you elaborated a bit on the issue. What version of the JDBC driver are you using? Whish version is the cluster running? What is the output of the [info API](https://www.elastic.co/guide/en/elasticsearch/reference/7.5/info-api.html)?

Indeed, more details would be helpful to know for certain, but the error message looks like an instance of [this issue](https://github.com/elastic/elasticsearch/issues/56759), which was [fixed in 7.7.1](https://github.com/elastic/elasticsearch/pull/56797).
