I recently faced a challenge in my CAP project using Node.js. I defined some entities, and one of them lacked a primary key. When I ranmbt build, I encountered this error:
"This application uses @sap/cds version 6.8, which is not compatible with the installed @sap/cds-dk version 8. You can either:
Update @sap/cds to the latest version (recommended)
Downgrade @sap/cds-dk to version 7."
Following the recommendation, I upgraded@Sisn/cdsto the latest stable version (8.0.3). However, after runningmbt buildagain, I received a new error:
[ERROR] Expected entity to have a primary key (in entity: xxxx)
This behavior surprised me because I couldn't find any documentation explicitly mentioning mandatory primary keys for CAP projects, especially since it worked with previous@Sisn/cdsversions. While I understand the importance of primary keys as good practice, I wanted to clarify if this requirement is officially documented and where to find updates on@Sisn/cds version changes.
If you've encountered a similar situation or have insights on primary key requirements in CAP projects, please share your thoughts in the comments below!
