The WRF model is unable to capture the regional precipitation

I am encountering an issue with my WRF simulation where it fails to produce any precipitation. I have configured and run the model for a specific domain of interest. Upon checking the output files, I found that the values for both RAINC and RAINNC are consistently zero throughout the simulation period.

However, a comparison with ERA5 reanalysis data for the identical time and location indicates significant precipitation. This discrepancy suggests a problem in my setup or configuration.
I would be grateful for any insights into the possible causes of this problem.
