Cannot overwrite data definitions with annotation.xml in Fiori Elements

[kaori_oiwa]

Hi,

I am currently using Fiori Elements and Guided Development to create an application.
In order to control the data type, number of digits, and attributes on the Fiori side,
I created an annotation.xml file using the Git source as a reference,
but the following error was output and the data definition was not reflected.
Could you please provide a solution to this problem?

Message:
Unknown Sub-Element: <EntityType> only [Annotations,Annotation] Sub-Elements are allowed xml-server

To Be:
I want to add data type, number of digits, and attribute conditions to a column in ProjectsEntity and reflect them in the input field of a filter.

Best regards,
