I got a raspberry pi with a json rpc server running on it. i used this module: https://github.com/bcb/jsonrpcserver

Everything is working fine when I only make a request to the following method:

@method
def ping(): 
 return "pong"

But when I want to go further and do other functions and things like

@method
def changeDisplay(): 
 self.led.clear_display()

Even when I do

@method 
def ping():
 self.helloworld()

def helloworld():
 print("helloworld") 

then I get a 500 error without further explanation.

request("http://192.168.2.5:5000", "ping")

Request looks like above I am stuck and have tried many different things.

Traceback:

UPDATE

Think it has something to do with the server not being async. All prints after server start are not printed

The methods of your class do not receive a self parameter, yet attempt to use it:

class Bartender(MenuDelegate):
 ...
 @method
 def ping():
 self.changeDsplay() # name `self` is not defined
 print (" TOkm")
 return " ewa"

The docs for jsonrpcserver and the source do not suggest that method can properly handle classes and their methods. It seems that you have to add the bound methods an instance, not the unbound methods of the class.

class Bartender(MenuDelegate):
 ...
 # regular unbound method taking `self` parameter
 def ping(self):
 self.changeDsplay()
 print (" TOkm")
 return " ewa"

 def run(self):
 # register bound methods *of this instance*
 method(ping=self.ping)
 ...
