Remote Agent Task Error: "Task was specified but does not exist"

### What happened?

When sending a message to a remote agent, the following warning and error occur:
```pgsql
🟡 Sending message to agent with taskId: 8cadbb68-77e5-4ead-85e7-b9ad98f565e2
🟢 send_message succeeded.
send_response {
"error": {
"code": -32001,
"message": "Task 8cadbb68-77e5-4ead-85e7-b9ad98f565e2 was specified but does not exist"
},
"id": "7ea0fb76-a16d-4c42-950d-b25f38e96d90",
"jsonrpc": "2.0"
}
```
This occurs even though send_message returns a success and a valid taskId was provided.

### Relevant log output
