Does anyone faced an issues of connection from KNIME to PowerBI?
Here is my workflow:
Even though it successfully connects to Power BI, but it does not display the complete dataset; it only shows the column headers.
PowerBI Service (web):
I tried to get data from the Power BI semantic model in Power BI Desktop, but it shows the same result — it does not display the complete dataset, only the column headers
PowerBI Desktop:

Did you try to put the data into a mysql or other database / file (excel/csv) and make a insert using connection inside the PIB to test it too? To understand the possibilities and limitations, if the problem can be the node or the data transfer/dataset?
Normally, I recommend to put the data into a database in cloud or local and consume it on demand, to not inject it directly into PBI and have some space and process problems.
Try and reply here please with news.
Thanks, Denis
