@Job de Noo this is most probably not related to sst. It seems like you are getting a non JSON response from your endpoint. Are you getting a proper response with cURL or postman? or if that's a get request you should be able to check that in the browser too
j
so end point should always return json?
a
depending on your setup but in this case it seems like there is something trying to parse that response as a JSON string
Copy code
SyntaxError: Unexpected token n in JSON at position 0

j
the method is just printing the event
if i return a dict with {'statusCode' : 200} it fails as wel because it says a set is not serializabe
a
Copy code
urllib.error.HTTPError: HTTP Error 400: Bad Request
c725cef9-e66c-4ffb-bc5c-5bad18ff538f ERROR Runtime exited with error: exit status 1
you also have this which means in general that you are missing some arguments
j
// Create a HTTP API     const api = new sst.Api(this, "Api", {       defaultFunctionProps: {         srcPath: "src",         runtime: "python3.8"       },       routes: {         "GET /": "handler.handle",       },     });     // Show the endpoint in the output     this.addOutputs({       "ApiEndpoint": api.url,     });
it should just handle a get on / right?
a
what does your function body look like?
j
def handle(event, context):     return json.dumps({'statusCode', 200})
i tried this
this return {'statusCode', 200}return {'statusCode', 200}
and just not returning anything
all valid responses for api gateway
a
Copy code
import json

def handle(event, context):
    return json.dumps(event, indent=2)
can you try this?
j
same issue
a
sorry had a mistake there it should be
Copy code
from __future__ import print_function
import json

def handle(event, context):
    print(json.dumps(event, indent=2))
j
prints the event but then fails
a
APIGatewayEvent
has a 
body
property which is already a JSON string so something like this might work for you
Copy code
import json

def handle(event, context):
    return event.body
j
with same error
a
I'm not entirely sure how to do that in python ))
also make sure you have proper permissions set for your function in your stack file
j
there shouldn't be any permissions right?
but sst can't support all cases api gateway supports?
a
not sure
look at the docs if you haven't already https://docs.serverless-stack.com/constructs/ApiGatewayV1Api and also try cloning and running this https://github.com/serverless-stack/serverless-stack/tree/master/examples/rest-api if it works for you then there something with the python function
j
this function can be deployed with cdk or serverless without issues
so don't think it is
return {'statusCode': 200 }
now works
don't understand why, earlier it did not
f
@Aram thanks for look into issue.
Hey @Job de Noo did you manage to resolve the issue?
a
@Job de Noo I think you were doing
Copy code
return json.dumps({'statusCode', 200})
wrapping it with json.dumps, maybe that's why?
