What Should I Do If Components Fail to Be Upgraded in ServiceStage Dark Launch?

Symptom

Components fail to be upgraded in ServiceStage dark launch. The following error information may be displayed:

• query microservice info failed, microservices should be registered.
• The grayscale service must be a new version.

Solution

1. Determine the failure cause based on the error information.
   • If the error message "query microservice info failed, microservices should be registered." is displayed, the component instance may not be a microservice or the component instance is not registered with CSE.
   • If the error message "The grayscale service must be a new version." is displayed, the component instance registered with CSE is not of the new version.

2. In Deployment Record, select a record that fails in dark launch.
3. Click Roll Back.
4. Rectify the fault based on the cause in 1.
5. Perform dark launch again and check whether it is successful.
   • If yes, no further operation is required.
   • If no, contact customer service.
