Unable to run StreamPipes for Core Development

What do you want to report?

I am trying to setup streampipes. I followed the documentation from this website - https://cwiki.apache.org/confluence/display/STREAMPIPES/Core
I did the following:

1. Cloned the github repository.
2. git checkout dev.
3. cd installer/cli && ./streampipes env --set backend.
4. ./streampipes up -d
5. Opened the Poject in IDE (IntelliJ IDEA).
6. There are 2 run configurations:
   A. core
   B. StreamPipesCoreApplicationMinimal
7. I ran core configuration.
8. I can see that the application is running on port 8030 with context path '/streampipes-backend'.
9. I opened http://localhost:8030/streampipes-backend/ in the browser.
10. I am getting 401 Unauthorized (visible in network logs) and a Whitelabel error page.
11. I have tried some other paths as well which are listed in UnauthenticatedInterfaces.java file. But, I am getting the same error for all of them.

I see the following logs in the console repeating. But, I think they are not relevant to the problem:

2024-01-08T21:40:15.858+05:30  INFO 84218 --- [pool-3-thread-1] o.a.s.s.SpServiceDiscoveryCore           : Could not find any extensions services, retrying (1/3)

Am I missing something or doing something wrong? Thank you.

Hi @himanshu-pareek,

thank you for reaching out to us.
It looks good to me the way you've done it.
Can you perhaps have a look at the environment variables that are set in IntelliJ for the core?

Cheers,
Philipp

HI @tenthe
These are the environment variables which are set for core run configuration in IntelliJ:

And the following is the complete run configuration for core:

Thanks

Hi @himanshu-pareek can you access the UI?
It seems the backend is running. It is normal that you get a 401 when accessing the backend directly without authentication. You can also check the output of the extension service running in Docker to make sure it can connect to the locally running backend.

Hi @dominikriemer
Thanks for the help. In the output of the command ./streampipes up -d, I can see that the URL of local docker is http://localhost/. I have opened the URL in the browser. And after some time of loading, I see a login page.
Is that the expected behavior? If yes, then what is the email and password to log in?

Thanks.

You can find the default credentials in the documentation: https://streampipes.apache.org/docs/try-installation/

I'll convert this issue to a discussion since it's probably not related to a bug.

I can see the dashboard. So, it worked. Thanks @tenthe and @dominikriemer for the help.

Closing the discussion as it is working as expected.
