Can't add composeExtensions?

[firstteam]

Here is my composeExtensions part..

"composeExtensions": [
{
"botId": "--MyBotID--",
"canUpdateConfiguration": true,
"commands": [
{
"id": "searchCmd",
"type": "query",
"title": "Search",
"description": "Search ....",
"initialRun": false,
"fetchTask": false,
"context": [
"commandBox",
"compose"
],
"parameters": [
{
"name": "searchKeyword",
"title": "Keywords",
"description": "Enter your search keywords",
"inputType": "text"
}
]
}
]
}
],

In App Studio, Import an existing app, I selected my zip that contains this manifest...

Then I got validation error...please check attached file. It is strange though..

I removed this part from the manifest file..then imported..then it was ok...then I could add this extension from the App Studio UI. ..Then it was working fine... I just compared the one that generated manifest preview in App Studio to mine...I didn't see any difference though..

Does that means the extension must be configured inside App Studio???? I doubt it though.

Thanks,

@firstteam - I have tried to upload manifest with your Compose Extension  array and it's working absolutely fine. I am not getting any error while uploading file in App studio. Could you please try this manifest.
