I have the Power BI Desktop RS Version as 1.5.7074.36177 (May 2019) and Power BI Report Server (Development version): 2.73.5586.1501 64-bit (September, 2019) When I try to save the report to PBI RS, it is throwing following error.
We can't save this Power BI Desktop report because either it is newer version
or has component parts that are not supported.
I was able to upload it previously and I am not sure what settings have changed. It started giving the above error.
