This suddenly stopped working with the error

It was working for more than 3 years. We are now on 7.10 (for more than 6 months, when the above script was working) ES version. But suddenly it started to fail.
The strange thing is that it is not happening in all environments. Is it some java version related or something else? We can not also reproduce this locally.
