Webhook connector - 401 error

[pragasekar]

I am trying to behavior of webhook with my local environment. I just deployed the simple workflow which starts based on webhook notification.
I deployed the process. whenever i hit the connector URL, i am facing 401 error. i am able to hit the other services by following the steps mentioned in Local installation with Camunda 8 Run | Camunda 8 Docs. But Inbound services are failing with 401

Env: Local environment using c8run

Hi @pragasekar
Can you show the Authorization settings that you use for the connector?

Regards,
Alex

Hi Alex,
I haven’t set any authorization type. Below the screen shot

[Alex_Voloshyn]

What if you follow the authentication instructions described in the Use Camunda APIs section?

[pragasekar]

With this i am able to use other operate-APIs. But for connecter service its failing with 401.

[Alex_Voloshyn]

I just tried a setup similar to yours and it works fine for me. The only difference is the operating system.

Can you share your BPMN file?

Regards,
Alex

[pragasekar]

Attached the bpmn file for the reference. I am using this with windows.
Could you specify your OS and tried BPMN file.

startWebHookTwo.bpmn (4.3 KB)

[Alex_Voloshyn]

I use Mac OS. I tried with your BPMN and it works fine.

[pragasekar]

Interesting. i am not sure we can conclude this as issue because of OS.

I am using the desktop modeler. I am not sure its something todo with modeler version. If you dont mind, could you share your BPMN content as xml and curl commands you have used.

I tried to run the same with docker version of C8. I am able to initiate the process without any issue. Sounds like there is some issue with windows version of c8run.

Thanks @Alex_Voloshyn for your time
