Greetings everyone,
The project in Camunda 8 - Develop Workers (Java) course won’t run after preparing the env as described in Prepare Environment step.
Last time, I had 404 error with this project, but I managed to solve it somehow.
Now I’m getting 401 even though following the steps, which is simply downloading the project and inserting the credentials.
The credentials are correct because:
- I have tried them with another application and also in Postman.
- I also tried debugging to check that the credentials used are the ones I inserted.
