Error when trying to add data via REST API to a dataset/table created via PBI desktop

[roalexan]

I have a customer who has created a dataset with two tables using the PBI desktop. The first table contains device data that will be streamed in on an ongoing basis. The second table contains lat/lon data that will be used as reference data to join with the first table, and only infrequently updated. He now wants to programmatically add data to the first table programmatially using the REST API. This fails with the following error:

{
  "error": {
    "code": "InvalidRequest",
    "message": "Posting rows to this type of dataset is not currently supported. Please create your dataset by posting it through the API following the instructions on http://dev.powerbi.com."
  }

Is he hitting an issue with PBI in that it doesn't support writing data using the REST API to datasets created via the PBI Desktop? Is this going to be fixed (and if so, when), or is there a suitable workaround?

Thanks, Robert

Yes, I believe that is exactly what he is hitting. Probably needs to post the PBIX file up to an Azure Power BI collection and then he could add the data programatically.

Hello. What do you mean by a "collection"? I just now tried to recreate the customers issue and I think I got it - although the error I got is "400 - Bad Request". Anyway, I created a dataset and table using PBIX and published it to my subscription. Then, I tried to add rows to it programmatically. This is when I get the bad request error. So, do people know if this should actually work - programmatically writing to a dataset/table that was created via PBI Desktop?

@roalexan, I get the same exception as yours when I try using Power BI REST API to add rows to dataset which was created in Power BI Desktop. I have to say that there is a limitation in the API that it is only supported to write data to datasets that were created via API.
