This is some weird bug I encountered today working both within VSCode and the BAS (SAP Business Application Studio), when opening the Fiori Studio (Show Page Editor, etc): ``` Annotation features are disabled - error while parsing annotations. ``` and ``` 2025-04-22 12:20:53.994 [error] Reading UI Nodes failed: Error: Could not compile service. Missing document file:///home/user/projects/my-project/node_modules/@sap/cds/common.cds ``` Finding the issue was quite a PITA. What caused the issue on our end was a service definition in a `.cds` file. Although `cds build` ran fine all the time, there seems to be a discrepancy in compilers. What fixed it was adding a semicolon after action definitions with the following format: ```js entity e as projection on E.e actions { action a() returns { p : Boolean; } // <-- here needs to be a semicolon! }; ```
