When I inspect the request this is the URL that failing:

"execution": {
"workflowId": "slack_playground",

},
"reason": "",
"id": "5",
"identity": "webui"
}

Response:
{
"code": 3,
"message": "temporalproto: (line 1:2): unknown field "execution""
}

To Reproduce
Steps to reproduce the behavior:

1. Start a workflow with an activity that will fail.
2. Server will retry and while it is waiting to retry again, click pause button in event history

⚠️ Known Issue: Activity commands (e.g., pause, unpause, update, reset) and workflow pause operations will return errors when using v2.45.4–v2.46.0 due to route collisions in API v1.61.0. Upgrade to v2.47.0 or later (which use API v1.62.2+) to resolve this issue.
