Failed to get_keyword_names!

[nouhab]

hi Team,
I try to run skuliLibrary framework under a docker file.
The scenarios is as follow:
1.Create a docker file

FROM node:14-alpine

RUN apk update \

  && apk add build-base python3

RUN mkdir /.npm \
  && chmod 777 /.npm

RUN apk add --update  py3-pip
RUN apk add openjdk11
# CHROME
RUN apk --no-cache upgrade && apk add --no-cache chromium chromium-chromedriver
RUN apk add libexif udev

# ROBOT + LIBRARIES
RUN pip3 install robotframework && pip3 install robotframework-selenium2library  && pip3 install robotframework-jsonlibrary && pip3 install robotframework-jsonlibrary &&  pip3 install robotframework-SikuliLibrary

RUN apk update && apk add bash

ENTRYPOINT ["/bin/terraform"]

2. docker build to build the image
3. docker run -it -d -P robotfram ==>-P option to forword all ports to the host machine which is a windows machine
4. docker cp "C:\Users\nboujelben\Downloads\test" sleepy_goodall:/home==>copy the test folder from local to my container
5. my test file named robot.test and it contains a simple example:

*** Settings ***

7.export DISPLAY=127.0.0.1:10.0 ==>create an env variable named DISPLAY
8. apk add opencv-dev
apk add tesseract-ocr
8. run a test as folow robot test.robot
9. I get this erreur:

hi, @nouhab
could you confirm the version installed in docker?
And do not need call "Start Sikuli Process" in test setup. sikuli process will be started when library is initialized by RF.

In new version, get_keyword_names do not connect remote server by default. so the error should not be like this.

[nouhab]

hi,
i have the last version installed in my docker file:

cat version.py
Created on 2015/12/10
Author: by wang_yang1980@hotmail.com
VERSION = '2.0.3'

when i remove the Start Sikuli Process i get this error :

Sikuli tests                                                          | FAIL |
Setup failed:
AttributeError: 'NoneType' object has no attribute 'run_keyword'

[rainmanwy]

could you execute test.robot with command "robot -L trace test.robot", and attach log here. And i think there is log.html and several sikuli log files.

[nouhab]

Thanks for your response .

[rainmanwy]

could check start server manually.
And check console output.

[nouhab]

i start the server manually by typing this command : nohup java -jar /usr/lib/python3.10/site-packages/SikuliLibrary/lib/SikuliLibrary.jar 8081 /home/test/img &

then i change my code to

*** Settings ***
Documentation     Sikuli Library Demo
Library           Selenium2Library
Library           SikuliLibrary  mode=NEW
Test Setup        Run Keywords

Unfortunally i still get the error AttributeError: 'NoneType' object has no attribute 'run_keyword'

[nouhab]

@rainmanwy Any suggestion to resolve the problem please ?

[rainmanwy]

i mean the console output of java process. actually most sikuli related keywords are implemented by java 获取Outlook for Android<https://aka.ms/AAb9ysg>

@nouhab, from the log, java process is started successfully.

you may use "Remote" library to call sikuli keywords. and check the console output of java process.

#18 99.80 [exec] Free TCP port is: 35565
#18 99.80 [exec] Start sikuli java process on port 35565
#18 100.9 [exec] Sikuli java process is started

#18 107.0 [exec] Traceback (most recent call last):

at least from the log, sikuli process is started with port 35565. but failed to get keywords from url http://127.0.0.1:35565/. maybe there are some error logs from java process.

here is sikuli process output:

and python test script
In [1]: from robot.libraries.Remote import Remote

In [2]: r = Remote('http://127.0.0.1:10000/')

In [3]: r.get_keyword_names()
Out[3]:
['setAlwaysResize',
'imageCount',
'returnMatchFromRegion',
'changeScreenId',
'captureRegion',
'doubleClickOnMatch',

I am having the same issue when trying to build with maven. Has this issue been concluded?

[rainmanwy]

@erdemkucuk , thank you for the report. How about your OS version, JDK version. have you tried "start server manually" method, is there some errors in the console output?

[erdemkucuk]

@rainmanwy, Hi I've tried this on Ubuntu 20.04 and tried both OpenJDK 11 and 17. Unfortunately teared down my setup and no longer able to access logs.

Hello to all,

I met a similar issue in the past (to be confirmed it it may solve yours). I’m working on Almalinux 8. I installed the opencv rpm package thinking it would install all libraries. When I ran SikuliXide.jar, everything worked as expected, but when I ran my own Robot frameword code, i got the error message you raised. In my case it was due to the fact that the Almalinux package was not providing the libopencv_java.so : this library is present in the Sikulixide.jar but not in the SikuliLibrary.jar, hence the difference in term of behaviour.

As a workaround, i unzipped the sikulixide.jar and retrieved the libopencv_java430.so (adapt version if necessary), i added it to my Dockerfile (add also a link from libopencv_java.so to libopencv_java430.so). The proper way would be to recompile it but i had few time and just wanted to check it was solving the issue. You may also need to add the library to the CLASSPATH environment variable.

Hope it helps.
