Dear All, I am facing below problem while returning the books, but it happens only in few users because when i return the same book after issue in other member it does not show the error. Koha 20.03 on Ubuntu. The member data has been imported into the Koha rather than manual entry. Software error: Can't call method "truncate" on an undefined value at /usr/share/koha/lib/C4/Circulation.pm line 1967. For help, please send mail to the webmaster ([no address given]), giving this error message and the time and date of the error. -- *With Regards,Vinod Kumar Mishra,Assistant Librarian,Biju Patnaik Central Library (BPCL),* *NIT Rourkela,* *Sundergadh-769008,* *Odisha,* *India.* *Mob:91+9439420860* *Website: http://mishravk.com/ <http://mishravk.com/>*
