Trouble with Document Error in Indexing

Hello, I'm getting an error while indexing. How do I find out which field is affected?

I20230831 08:13:32.846366    25 index.cpp:504] Error while validating document: [json.exception.type_error.302] type must be number, but is array

Check the api response. You can also send ?return_id=true parameter so that id of the record is returned.

the API response is just

{
    "message": "[json.exception.type_error.302] type must be number, but is array"
}

That's odd. It seems like the exception happens in an unintended place.

I had an int32[] field that I was trying to feed an array of strings.

Update or new insert?

new insert

Ok thanks for the info, I'll check

If you need more info to reproduce let me know

Hauke I just tried to recreate this issue on a simple collection but I get a proper error message:

{"message":"Field `points` must be an array of int32."}                                                                                                                                                     

It will be great if you can post a full example code snippet.

I will try to find a minimal reproducible data set

Thanks
