Analyze with custom analyzer throws JsonGenerationException

Elastic Stack Elasticsearch

Hi

I have the same problem than the unanswered one there

Refering to the doc Java High Level REST Client, I built a custom analyzer

AnalyzeRequest request = new AnalyzeRequest();
request.text("<b>Some text to analyze</b>");
request.addCharFilter("html_strip");                
request.tokenizer("standard");                      
request.addTokenFilter("lowercase");

Though, when I run the anayze

client.indices().analyze(analyzeRequest, RequestOptions.DEFAULT)

I get the following exception:

Exception in thread "main" com.fasterxml.jackson.core.JsonGenerationException: Can not write a string, expecting field name (context: Object)

Everything works well if I use a built-in analyzer.

Thanks in advance for your anwser,
M.

You'r welcome!

For thoses interested by analyse on the fly, I overcomed the current limitation using an analyzer defined in an index I first put in ES with the custom analyzer I needed.
This as proposed in the same doc section.
