One of my customer's GSTN is suspended , I came to know about this when I uploaded GSTR1 return json file and error report was generated stating "GSTIN of recipient is inactive " .

What should I do ? Should I just continue to file GSTR1 by filing their invoice in B2C ? or should I wait, in case in near future his GSTN might get activated again .

What should be correct course of action in this situation  ?
