Perl Error - Error: Filehandle GEN0 opened only for output at Task.pm line 103.

Error:
Filehandle GEN0 opened only for output at Task.pm line 103.

Solution:
(W io) You tried to write on a read-only filehandle. If you intended it to be a read-write filehandle, you needed to open it with +< or +> or +>> instead of with < or nothing. If you intended only to write the file, use > or >>.
