Unknown Message Id

[Sarthak-uptiq]

Describe the bug
I am trying to use the ext-apps sdk in my Agentic application. But I am encountering these errors while using AppBridge when I send notifications to the app. When I send notifications from the host to the inner iframe I get these errors everytime Error: Received a response for an unknown message ID: {"jsonrpc":"2.0","id":1,"result":{}}. Not able to understand why do I get these errors

To Reproduce
Steps to reproduce the behavior:

1. Initialize AppBridge
2. Try sending any notification from host for eg:

appBridge.sendToolResult({
        content: [],
        structuredContent: toolResult
    });`

Expected behavior
Instead such errors should not be thrown and the mcp app must process these notifications

Logs
Refer the example error message I provided.

Hi @Sarthak-uptiq , thanks for your report!

The only repro I could find for this involved connecting the same AppBridge twice. Do you think that might be happening here? (or could you share a complete repro?)

Sending #450 to detect that potential failure mode earlier anyway :-)
