FPR Upload shows Error Processing - FMDAL Exception

Hi,

I'm trying to upload FPR in Fortify SSC but the UI shows Error Processing - FMDAL Exception

Exception: An unexpected error occurred during scan processing: com.fortify.manager.exception.FMDALException: Unable to execute batch.

I tried to clear some old fprs and versions in other applications so that some space is cleared .. but no luck.

Can you please guide, how to fix this
