Error to render compiling AST KeyError: 'digits'

[bitsnaps]

Hi,
I got an error when trying to print Manufacturing Order Report in MRP module at smile_decimal_precision/report/ir_qweb.py, it says Error to render compiling AST KeyError: 'digits', looks like there is no digits key in self.env, wouldn't be better to check if digits key available first?

odoo_addons/smile_decimal_precision/report/ir_qweb.py

Line 11 in 3ad7f33

record._fields[field_name].get_description(self.env)['digits'] or \

Using: Odoo v11.0 CE.
