Unable to execute addStreamEntries

[chaitanya]

I have assigned a dataShape(without a primary key) to a stream but whenever I try to edit value field to add multiple stream entries. I get a response saying "Must have a dataShape defined to add rows. "(Please find attached screenshot)

When tried with a single addEntry, it works fine.

It looks like you are trying to execute this within composer.

Unfortunately it looks like this is one of those services that doesn't run within composer.

You will have to do an actual service call.

Hi @PaiChung,

Thanks for the response.
Do you mean to say I have to invoke this service with a REST call?
If so, what would be the json structure for sending multiple entries?

I tried using below service. It executes successfully but when GetStreamEntriesWithData is called, I am unable to see any added entries.

It doesn't look like you are doing anything wrong, although infotable inside of infotable is tricky.

I'd recommend you create a support ticket for this.
