Remember, an issue is not the place to ask questions. If you have issues with the APIs or have a question about the Watson services, see Stack Overflow.

Before you open an issue, please check if a similar issue already exists or has been closed before.

Check service status

1. For service issues or 5xx errors, first, go to the IBM Cloud status page and check the status of the service.
2. If the service status is OK, continue with a bug report.

@Lpourchot thanks for opening the issue, can you please provide a code snippet of how you are using the SDK?

[Lpourchot]

Hello, as mentioned in the API doc :https://cloud.ibm.com/apidocs/natural-language-understanding?code=python

!pip install --upgrade "ibm-watson>=5.0.0"

[Lpourchot]

and get : Successfully installed ibm-cloud-sdk-core-1.7.3 ibm-watson-5.0.2

[mamoonraja]

That does not give me all the info to debug though, can you confirm whether you replaced the API key properly and set the service URL?
