Hi MOSIP team,

All core modules and the other pre-registration micro-services start fine, but prereg-application keeps restarting.

i think below is the reason for that.

**MasterDataNotAvailableException (KER-MSD-016) “Valid document not found”**

below are the error logs

io.mosip.preregistration.core.exception.MasterDataNotAvailableException: KER-MSD-016 → Valid document not found  
at io.mosip.preregistration.core.util.ValidationUtil.getAllDocCategoriesAndTypes(ValidationUtil.java:340)

Hi @Tharindu_Kavinda

Could you please confirm which version of the `masterdata-loader` you have executed? Also, kindly check the `masterdata-loader` logs to ensure it has completed successfully.  
From the observations, it appears that the issue might be related to the `masterdata-loader`, which could be affecting the `prereg-application` service.

Best Regards  
Team MOSIP

Hello @Tharindu_Kavinda,

Thank you for your query.

To help investigate the issue further, could you please provide the following details:

1. **Full log stack trace** from the time the error occurred.
2. **Configuration properties** (i.e. application properties or YAML) used for the **Pre-Registration modules** , including:

- prereg-application-service
- or any other relevant modules used in your setup

This information will help us identify the root cause and provide accurate assistance.

Best regards,  
MOSIP team.
