RAP - READ EML Statement is not fetching any results but it is calling the FOR READ Method

Hi Experts,

I'm implementing RAP unmanaged scenario, I'm writing the READ EML statement in the custom ACTION method. Still, I'm not getting any results and this READ statement is calling my FOR READ method of the class. I have written the same READ statement inside my FOR READ method as well but there also it is not fetching any results.

Please let me know if there is any solution for this,

P.S. I'm using the custom cds entity to fill the initial data.
