Check Method Existence: Ensure that the method specified in the error message exists in the class and is correctly defined.
- Check the method's visibility (public, protected, private) to ensure it can be accessed as needed.
Review Configuration: Go through the configuration settings where the class and method are defined. Make sure they are set up correctly.
Transport Check: If the configuration was transported, ensure that all necessary objects (classes, methods) were included in the transport request and successfully imported into the target system.
Namespace Verification: Confirm that the class is in the correct namespace and that there are no conflicts with other classes.
Debugging: If the issue persists, consider debugging the code to trace where the error occurs. This can provide more context on why the class or method is not being recognized.
