Saludos amigos.
He creado un report y al imprimir me sale el siguiente error.
Traceback (most recent call last):
File “/site-packages/trytond/wsgi.py”, line 47, in dispatch\_request

context[‘set\_lang’] = lambda language: translate.set\_language(language)
TypeError: ‘NoneType’ object does not support item assignment
Mi clase report es la siguiente:
class SalesExpensesReport(Report):
‘Sales Report’
**name** = ‘sale\_pos\_report.expenses\_report’
```
@classmethod
def get_context(cls, records, data):
report_context = super(SalesExpensesReport, cls).get_context(records, data)
pool = Pool()
Estado = pool.get('account.statement')
estados = Estado.search([
('date', '>=', data['desde']),
('date', '<=', data['hasta']),
])
sum_total_amount = []
sales_filtered = []
for estado in estados:
for linea in estado.lines:
if linea.amount < 0 and (linea.statement_state in ('posted','validated')) and linea.sale==None:
sales_filtered.append(linea)
sum_total_amount.append(linea.amount)
report_context['records'] = sales_filtered
report_context['sum_total_amount'] = sum(sum_total_amount)
report_context['desde'] = data['desde'].strftime('%d-%m-%Y')
report_context['hasta'] = data['hasta'].strftime('%d-%m-%Y')
```
Estoy usando tryton 4.2
El mensaje menciona “language”, sin embargo este reporte lo modifique de otro que funciona normalmente, si pueden darme una opinión al respecto estaré agradecido.
Saludos
Fernando

You forget to `return report_context`
