Rename the sde connection file to start with an alpabet. Also could you copy the SDE file to a shorter, non-OneDrive path with no space or special characters in pathname.
e.g.:
D:\GreenDestinations\CSM5432.sde
@JayantaPoddar Hi again, I have tried everything and still get this message. Does anyone else had this problem before? Thanks
@JayantaPoddar Thank you for your message. I have tried it and it still doesn't work.
I'm having this issue as well... Has anyone found a resolution?
@IB3 and @moremeowbell or if anyone else is still facing this challenge like I did just now. I found this resource to be very helpful. You can take a look at this here - https://pro.arcgis.com/en/pro-app/latest/help/data/databases/add-the-st-geometry-type-to-a-postgresq...
This solved my issue. Apparently, ArcGIS requires some special permission in the DB.
