I am using Python version 3.7.0. Please help.

[HardNorth]

@manvendravsingh that means your server didn't response with a JSON. Could you please describe how you configure your agent?

[manvendravsingh]

I am using demo report portal. I have update my pytest.ini with following settings.
rp_endpoint = https://demo.reportportal.io/asd
rp_api_key = ******************************************************
rp_project = default_personal
rp_launch = *********************

Then as suggested in readme I have created rp_logger -

from reportportal_client import RPLogger

@pytest.fixture(scope="session")
def rp_logger():
    logger = logging.getLogger(__name__)
    logger.setLevel(logging.INFO)
    logging.setLoggerClass(RPLogger)
    return logger

and using this logger in my pytest Tests. as -

@pytest.mark.usefixtures("setup")   # Setup is just someother fixture printing Hi as of now. 
class TestSample:
    def test_sampleTest1(self,rp_logger):
        rp_logger.info("This is Sample Test 1")
        assert True

now I am executing the test cases using command - pytest --reportportal

Please let me know if I am missing something.

[rplevka]

rp_endpoint = https://demo.reportportal.io/asd

remove the /asd.

[manvendravsingh]

Thanks for reply. I am able to send test results on demo site now.

Now, I have applied same changes in live project and I am facing the same issue. The main difference is that, In my live project has reportportal is deployed our port 8080 so I have to use the rp_endpoint= http://myliveprojectsite.com:8080.
But when I doing this I am facing the same JsonDecodeError.

I have tried to connect without giving the port then server is refusing the connection. (as expected)

It seems like while parsing the port in endpoint JsonDecoder is failing. Please help .

@manvendravsingh When I test the agent locally I also use port 8080 and that's cause no issue. So I would check that your instance actually working.

[rplevka]

@manvendravsingh i'd rather have this issue closed as this is really only some misconfig.

Is your instance really reachable at the provided url (E.g. from a browser)?
Since this is a new deployment, have you updated the API token?

If you are still facing issues, please, kindly post theis kind of requests to the community slack.
Good luck and thanks for understanding.

[manvendravsingh]

My instance is reachable. It is working fine with Python-reportportal 1.0.2 . I am trying to update to new version. Is it required to update the instance also ?

[HardNorth]

@manvendravsingh So you are using custom solution, that explains a lot. I believe you need to double-check your URLs, there's no any different reason to get such error, except invalid URL (on working instance). Even incorrect credentials return JSON response.

[rplevka]

@manvendravsingh you can place a breakpoint here and see what is inside the response (data.text).
That will give you a hint.
@HardNorth, we might wrap that inside a try-except block and append the text of the response in the Error to help users to figure out what is going on (in the future)

[HardNorth]

@rplevka I don't like exposing responses on our level of abstraction, there are HTTP logging properties which is regulated by chosen HTTP clients, which should be responsible for that. But I added better JSONDecodeError logging for our response classes here:
https://github.com/reportportal/client-Python/blob/d9fe80a4589a99019b48e5b618a4b1df0bd00de7/reportportal_client/core/rp_responses.py#L44C5-L44C35

I believe this resolves the issue.
