Hello Everyone, I have a trouble.
This is my logs

Some of the data I have found are of type errors. Some say there is a length limit. From the log, it is too long. Is there any restriction on elasticsearch?
help! thanks.

Hm, I think it's some kind of parsing issue with the document. Do you have a copy of a doc that causes this problem? This exception:

Can't get text on a START_OBJECT

Makes me think there is something malformed about the JSON. The exception about length is a red herring; when an IndexRequest is turned into a string for logging purposes, there's a limit on how large that string can be:

github.com

elastic/elasticsearch/blob/master/server/src/main/java/org/elasticsearch/action/index/IndexRequest.java#L562-L575


public String toString() {
    String sSource = "_na_";
    try {
        if (source.length() > MAX_SOURCE_LENGTH_IN_TOSTRING) {
            sSource = "n/a, actual length: [" + new ByteSizeValue(source.length()).toString() + "], max length: " +
                new ByteSizeValue(MAX_SOURCE_LENGTH_IN_TOSTRING).toString();
        } else {
            sSource = XContentHelper.convertToJson(source, false);
        }
    } catch (Exception e) {
        // ignore
    }
    return "index {[" + index + "][" + type + "][" + id + "], source[" + sSource + "]}";
}

That's just a safety feature, to prevent 100mb documents/bulk requests from blowing out the log with gigabytes of text as it serializes the entire document. It also saves a bunch of heap memory.

So you can ignore that exception, I think the real issue is that "Can't get text" exception.

Thank you for your reply. I have found the problem. I did not specify mapping. The default text of the field is longer than the length.
