my trytond.conf file:


[database]
uri = postgresql://psk:xxx...@127.0.0.1:5432/
path = /var/lib/trytond/
language = es_CO
retry = 5


[session]
timeout = 6000
super_pwd = xxxxxxxxxxx


[web]
listen = *:8100
hostname = 127.0.0.1
root = /var/www/localhost/tryton


So postgresql is running fine:

psk@psk-SAMS:~$ ps -Af | grep postgres
postgres 4100 1 0 11:04 ? 00:00:00
/usr/lib/postgresql/9.5/bin/postgres -D /var/lib/postgresql/9.5/main -c
config_file=/etc/postgresql/9.5/main/postgresql.conf
postgres 4102 4100 0 11:04 ? 00:00:00 postgres: checkpointer
process


1. Somebody has the same problem?,

2. How can I improvement the traceback output?

3. Is it a bug?


Thanks for advance.

Here the result:

TypeError: the JSON object must be str, not 'bytes'

I think that the problem is self.decoded_data variable because is type "bytes", I added a "print" before this line and I could confirm this, so
when I convert this variable using .decode("utf-8"), the problem was solved!.

Do I create  an new issue?
