Possible fdk-node on K8S issue?

[petecj2]

Hi there,

I'm running fn on a K8S cluster and can run through the Go instructions just fine:

https://fnproject.io/tutorials/Introduction/

But when following their Node equivalent:

https://fnproject.io/tutorials/node/intro/

The fn invoke nodeapp nodefn sends back a 500 error and the fn list calls comes back empty. Here's a full set of commands I'm running with results:

PETERCJO-M-63N9:fn petercjo$ fn init --runtime node --trigger http nodefn

PETERCJO-M-63N9:nodefn petercjo$ fn list calls nodeapp nodefn
PETERCJO-M-63N9:nodefn petercjo$

The only thing I did differently, and had to do the same on the Go example, was I didn't use the --local flag on the deploy command since I'm running on a remote K8S cluster instead of my local Docker.

Thoughts? Other logs I should be looking at?

I'd be happy to post a similar output for the successful set of Go commands if that'll help.

Can you provide the following :

Fn version (client and server version)
Node FDK version (from generated package.json)

The ‘format’ field in your func.yaml

[petecj2]

NP, here's the version output:

$ fn version
Client version is latest version: 0.5.13
Server version:  0.3.570

Contents of func.yaml, which I left untouched from the init command invocation:

$ more func.yaml
schema_version: 20180708
name: nodefn
version: 0.0.2
runtime: node
entrypoint: node func.js
format: http-stream
triggers:
- name: nodefn-trigger
  type: http
  source: /nodefn-trigger

@zootalures I guess, helm charts from the tutorial request IOFS configuration, no?
