JSON Serialization Issue

[fmatak]

I have below code:

AssistantsClient ac = openAI.assistantsClient( ) ;
var aclist = ac.listAssistants( PaginationQueryParameters.none( ) ) ;
String jsonString = ObjectMapperSingleton.getInstance( ).writeValueAsString( aclist ) ;

This jsonString is not valid JSON. The "tools" array is as follows:
"tools":[{"type":"file_search","type":"file_search"}]

Notice the duplicate type fields. I managed to get rid of the duplicate by modifiying the current annotation:
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, property = "type")
to
@JsonTypeInfo( use = JsonTypeInfo.Id.NAME, property = "type", include = JsonTypeInfo.As.EXISTING_PROPERTY )

merging this change (and maybe updating other classes for similar issues) could be helpful.

Thank you. This is indeed a bug. Fixed it in 1208a1b . Will be part of the next release.
