Resolution
This error typically points to a situation where the project is incompletely created on the backend, often resolving itself after a few hours. The underlying cause may involve incorrect DSNs or DSNs still undergoing processing.
Wait for Backend Processing: The error may resolve itself after a few hours as backend processes complete the project setup.
Verify DSNs: Ensure correct and properly configured DSNs.
Direct DSN Initialization: If the issue persists with a new project, consider specifying the DSN string directly in the initialization if using a dynamic variable.
