Hi all,

 

Getting error while executing AddStreamEntries service: 

JavaException: java.lang.Exception: Invalid number of values provided to AddStreamEntry

 

 

 

let newEntry = {
		sourceType: undefined, // STRING
		values: entries, // INFOTABLE
		location: undefined, // LOCATION
		source: undefined, // STRING
		tags: undefined, // TAGS
		timestamp: new Date() // DATETIME
	};
	// CreateInfoTableFromDataShape(infoTableName:STRING("InfoTable"), dataShapeName:STRING):INFOTABLE(StreamEntryWithValues)
	let obj = Resources["InfoTableFunctions"].CreateInfoTableFromDataShape({
		infoTableName: "InfoTable",
		dataShapeName: "StreamEntryWithValues"
	});
	obj.AddRow(newEntry);

	me.AddStreamEntries({
		values: obj /* INFOTABLE {"dataShape":"StreamEntryWithValues"} */
	});

 

 

 

Thanks,

Sujith

use below service

 

Things["TestStream"].AddStreamEntries({
	values: dataset/* INFOTABLE */
});

 

"dataset" is the nested infotable as below, which uses "StreamEntryWithValues" datashape.

In "StreamEntryWithValues" datashape, there is one infotable field called "values" 

In "values" infotable, you will have your own data set.

Each row consider as one entry in stream.

 

Hope it helps

//TestValuestream is the value stream name

let values = Things["TestValuestream"].CreateValues();
values.x = new Date(); //your datashape fields
values.y = 10; //your datashape fields
let params = {
 tags: undefined,
 timestamp: new Date(),
 source: me.name,
 values: values,
 location: undefined
};
Things["TestValuestream"].AddStreamEntry(params);

result = values;

 

try above code

Hi @Sathishkumar_C ,

 

I want to add multiple entries to the Stream at once, not only one entry.

 

Thanks,

Sujith
