I got it 

for record in self:

        if record.x_studio_end_date and record.x_studio_start_date:

                record['x_studio_number_of_days'] = (record.x_studio_end_date - record.x_studio_start_date).days

Hi,

Seems one of the fields is coming as empty, thus you get this error. In order to overcome the error add if condition and make sure that both the field contains value before subtracting them.

for record in self:

        if record.x_studio_end_date and record.x_studio_start_date:

                record['x_studio_number_of_days'] = record.x_studio_end_date - record.x_studio_start_date


Thanks
