I found similar failures on 20.5. on 8.2 (https://gradle-enterprise.elastic.co/s/md2ogoludqyjs) and same day on 7.17 (https://gradle-enterprise.elastic.co/s/3cyscee3ys6tq)

I extracted the root cause for better readability:

"root_cause":[{"type":"action_request_validation_exception",
"reason":"Validation Failed: 1: parent histogram of serial_diff aggregation [d] must have min_doc_count of 0;",
"stack_trace":"[Validation Failed: 1: parent histogram of serial_diff aggregation [d] must have min_doc_count of 0;]; 
nested: ActionRequestValidationException[Validation Failed: 1: parent histogram of serial_diff aggregation [d] must have min_doc_count of 0;];
