istSOS on debian 9.11 does not work (TypeError: the JSON object must be str, not 'bytes')

[Olivier Lobry]

Hi,

I'm trying to install istSOS 2.4.0-RC4-1 on a debian 9.11 with python 3.5.3

The installation worked fine and I am able to access the interface. 

But when I try to change any parameter (Service Provider, ...) or test the database connection, the application is stuck ("please wait" message) and I have this error in the apache log :

Looks like in the executeWa function (/usr/share/istsos/application_walib.py), wsgi_input is equal to 'None', meaning the application cannot read HTTP input (?) 

        "wsgi_input" : environ['wsgi.input'].read(int(environ["CONTENT_LENGTH"])) if environ.get("CONTENT_LENGTH") else None,

That leads latter to a bug in /usr/share/istsos/walib/resource.py :

     self.json = ut.encodeobject(json.loads(waEnviron['wsgi_input']))

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

Did anyone managed to install the application on a debian 9.11 or has an idea of the problem ?

Best regards

Olivier
