Completion suggester - java API - Suggest Response[Error: Can not write a field name, expecting a value]

LudoN4R4 · September 10, 2013, 8:56am

Hello,

I try to work with the new completion suggester (0.90.3) through java API,
but i get this error :

Suggest Response[Error: Can not write a field name, expecting a value]

This a sample code that i execute :

//client is a transport client
client.prepareSuggest("myIndex")
.addSuggestion(new CompletionSuggestionBuilder("")
.field("tag")
.text("foo")
.size(10))
.execute().actionGet();

If i use "prepareSearch" instead of "prepareSuggest" this work
correctly (searchs results+suggestions).

Thanks in advance,

ludo.

Could you please post the stacktrace of the error you get back? You should
see it in the elasticsearch log too.

Thanks

Sorry Luca but there are no stacktrace. I've noted that this error is not
due to the request himself but "just" to the "toString" method fromSuggestResponsehttps://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/action/suggest/SuggestResponse.java(which catch the error and pretty print it)

I could retrieve my "completions informations" but i've the mentionned
error if i try to outprint directly the response object (it's not blockingfor me).

This is my test code (scala):

*//client is a transport client*
*val* suggestResponse =  client.prepareSuggest("myIndex")
                                 .addSuggestion(*new*CompletionSuggestionBuilder("test_case")
                                                      .field("tag")
                                                      .text("foo")
                                                      .size(10))
                              .execute().actionGet();

 *//print suggest response to console*
 println(suggestResponse) *// Suggest Response[Error: Can not write a

field name, expecting a value]*

 *// Get completion values*
 *val* it =

suggestResponse.getSuggest().iterator().next().getEntries().get(0).iterator()

 *while* (it.hasNext()) {
    println(it.next().getText()) *// works fine print each expected

fields*
}

Hi,
thanks to your reply I was able to understand where the problem was.
Nothing blocking, but still a bug in the SuggestResponse#toString method,
which was throwing that exception all the time.

I created an issue for this:
JsonGenerationException thrown in SuggestResponse#toString method · Issue #3661 · elastic/elasticsearch · GitHub . Just pushed a
fix as well, it will be in the next release.

Thanks for reporting this

Cheers
Luca
