UI-Server - unknown method

Today I have taken the latest code from the ui-server and deployed the application.
When I select the workflow, it doesn’t show the summary / history.

What could be cause the issue?


“code”: 12,
“message”: “unknown method GetWorkflowExecutionHistoryReverse for service temporal.api.workflowservice.v1.WorkflowService”,
“details”: [

Looking into this,

What is your Temporal Server version?

Temporal Server Version: 1.15.2

currently the UI requires Temporal v1.16+ which adds reverse history API for the UI
