    In case this helps anyone else. I now have a better understanding of the issue above.

     

    The root of the issue seems to have been that for the Dataset that was being passed in to the API request, the owner was the publisher of the report (which it support) and it wasn't the master account.

     

    Once the master account took over ownership (you can do this from the Power BI portal > Select your Workspace > Datasets > On the Dataset of interest, go to Settings > Take over), the embed token was issued correctly.

     

    The effective user name that is being passed in does not seem to have any role to play until, the embed token is used to render the report.

     

    Note: I still don't know what DMTS means, but the issue is now resolved.

Hi Robbe ,

 

I can't tell for sure why you get this error, but it seems related to the data sources settings.

I would try to see if everything seems to be set correctly in the dataset settings page in Power BI portal. 

Maybe try to refresh the data in the dataset and see that it works as expected.

Hi,

Thank you for the fast reply. This error seems to be there for over 5 years and we still have no idea what it is? 😕 
My dataset contains all import datasources, so I dont see why this should impact an export to PDF?
Like I mentionned, connecting with paginated reports or running a daxquery on hte exact same dataset is not an issue...
