Problem description

VariableWidthHistogramAggregation is missing script field. I have alread checked ES support script field when we search histogram data like below.

GET test-index/_search
{
  "size": 0,
  "aggregations": {
    "factors": {
        "variable_width_histogram": {
            "field": "testField",
            "script": "Math.log10(_value)",
            "buckets": 100
        }
    }
  }
}

However, ES API client doesn't seem to support the script field yet.

elasticsearch-java/java-client/src/main/java/co/elastic/clients/elasticsearch/_types/aggregations/VariableWidthHistogramAggregation.java

Lines 238 to 245 in 8e4db1d

	protected static void setupVariableWidthHistogramAggregationDeserializer(
	ObjectDeserializer<VariableWidthHistogramAggregation.Builder> op) {
	op.add(Builder::field, JsonpDeserializer.stringDeserializer(), "field");
	op.add(Builder::buckets, JsonpDeserializer.integerDeserializer(), "buckets");
	op.add(Builder::shardSize, JsonpDeserializer.integerDeserializer(), "shard_size");
	op.add(Builder::initialBuffer, JsonpDeserializer.integerDeserializer(), "initial_buffer");

I use the histogram API in log scale, so can this API supports script field?

Hello, thanks for reporting this! You're correct, it seems like the field is missing from the API specification used to produce the Java code. It will be added soon and then the java code will be updated to solve the issue.
