I am trying to upload a simple JSON file  
{  
"address":{  
"serviceLocationId":"873784937",  
"billerLocationId":"2234243",  
"locationType":"RESI",  
"dwellingType":"SINGLE",  
"taxGeoCode":"2342325"  
}  
}  
but getting following error:

[illegal\_argument\_exception]: Could not find a timestamp in the sample provided

Explanation so far:

[Using character encoding [UTF-8], which matched the input with [15%] confidence - first [8kB] of input was pure ASCII]

[Not NDJSON because there was a parsing exception: [Unexpected end-of-input: expected close marker for Object (start marker at [Source: (org.elasticsearch.xpack.textstructure.structurefinder.NdJsonTextStructureFinderFactory$ContextPrintingStringReader); line: 1, column: 2]) at [Source: (org.elasticsearch.xpack.textstructure.structurefinder.NdJsonTextStructureFinderFactory$ContextPrintingStringReader); line: 1, column: 3]]]

any help?

It looks like a timestamp field is required when uploading a json file, ["For structured file formats, it is not compulsory to have a timestamp in the file"](https://www.elastic.co/guide/en/elasticsearch/reference/current/ml-find-file-structure.html)

There is an [open issue for uploading json without at timestamp](https://github.com/elastic/kibana/issues/63526) to allowing uploading files without timestamps. Please comment on this issue.

As a work around, maybe you could add a timestamp field?

Thanks.
