Hi Developers!
I have two streams, A stream and B stream, and their data shape are the same.
I've tried to add a part of stream data from A stream to B stream by using service addstreamentries.
But it kept saying Wrapped java.lang.NullPointerException Cause: null
Can someone help me? Appreciated!

Hello, can you please provide the JavaScript syntax you are using to attempt this copy?
var params = {
oldestFirst: undefined /* BOOLEAN */,
maxItems: undefined /* NUMBER */
};
// result: INFOTABLE dataShape: "undefined"
var a = me.GetStreamEntriesWithData(params);
var params = {
values: a /* INFOTABLE */
};
// no return
Things["BStream"].AddStreamEntries(params);
Hi Lee Wei,
The output format for GetStreamEntriesWithData service and the input format for AddStreamEntries service is different.
Please refer to following Blog for your answer to your query: How to copy entries from one Stream to other Stream
I hope it helps.
