feliu opened a new issue #2615: Python 3.6.1 action not writing logs when
print('something') on Ubuntu 14 LTS
URL: https://github.com/apache/incubator-openwhisk/issues/2615
I have an issue using the Python 3.6.1 action. The actions work correctly
but doesn't print anything in the log when using print or even when making a
syntax error making difficult to trace the errors when developing the function.
## Environment details:
* Native ubuntu 14.04.3 LTS following this sequence of instructions
https://github.com/apache/incubator-openwhisk/tree/master/tools/ubuntu-setup
## Steps to reproduce the issue:
1. Create this Python function:
```
import json
import sys
import platform
def main(dic):
try:
print("hello")
return {'result': platform.python_version()}
except Exception as e:
return {'error': str(e)}
```
2. wsk action create facebook_api --kind python:3 __main__.py
3. wsk action invoke facebook_api --blocking
```
ok: invoked /_/facebook_api with id 2a68e2200f5d4187aa70f577e37fe1bb
{
"activationId": "2a68e2200f5d4187aa70f577e37fe1bb",
"annotations": [
{
"key": "limits",
"value": {
"logs": 10,
"memory": 256,
"timeout": 7200000
}
},
{
"key": "path",
"value": "guest/facebook_api"
}
],
"duration": 725,
"end": 1502682035696,
"logs": [],
"name": "facebook_api",
"namespace": "guest",
"publish": false,
"response": {
"result": {
"error": "The action failed to generate or locate a binary. See
logs for details."
},
"status": "action developer error",
"success": false
},
"start": 1502682034971,
"subject": "guest",
"version": "0.0.7"
}
```
4. Now erase the line --> print("hello")
5. update and invoke..
```
ok: invoked /_/facebook_api with id be44e2456322437da4efa2e034d9a354
{
"activationId": "be44e2456322437da4efa2e034d9a354",
"annotations": [
{
"key": "limits",
"value": {
"logs": 10,
"memory": 256,
"timeout": 7200000
}
},
{
"key": "path",
"value": "guest/facebook_api"
}
],
"duration": 736,
"end": 1502682215005,
"logs": [],
"name": "facebook_api",
"namespace": "guest",
"publish": false,
"response": {
"result": {
"result": "3.6.1"
},
"status": "success",
"success": true
},
"start": 1502682214269,
"subject": "guest",
"version": "0.0.9"
}
```

Is anybody finding troubles to output logs from stdout or stderr in Ubuntu
native installation using CouchDB and Python 3.6.1 actions?
Thanks to all for the help!
