My application was using the Watson Conversation API (21st Apr 2017 version) imported as a maven dependency:
<dependency>
<groupId>com.ibm.watson.developer_cloud</groupId>
<artifactId>conversation</artifactId>
<version>3.9.1</version>
</dependency>
I've checked the credentials (username and password) for correctness. However, it is still giving me the following error (I've replaced the actual conversation workspace id with the placeholder ACTUAL_WORKSPACE_ID in URLs):
Feb 12, 2020 6:14:40 PM okhttp3.internal.platform.Platform log INFO: <-- 401 Unauthorized https://gateway.watsonplatform.net/conversation/api/v1/workspaces/ACTUAL_WORKSPACE_ID/message?version=2017-04-21 (342ms, 37-byte body) Feb 12, 2020 6:14:40 PM com.ibm.watson.developer_cloud.service.WatsonService processServiceCall SEVERE: POST https://gateway.watsonplatform.net/conversation/api/v1/workspaces/ACTUAL_WORKSPACE_ID/message?version=2017-04-21, status: 401, error: Unauthorized Exception in thread "main" com.ibm.watson.developer_cloud.service.exception.UnauthorizedException: Unauthorized: Access is denied due to invalid credentials. Tip: Did you set the Endpoint? at com.ibm.watson.developer_cloud.service.WatsonService.processServiceCall(WatsonService.java:410)
I observed that the newer version of APIs is available and the IAM & Resource groups have been introduced in the IBM Cloud. Is this issue a result of these changes? Can we not use the older API any more?
