Manifest parsing error when trying to test app in Teams - microsoft-teams

Question

From https://dev.teams.microsoft.com/, whenever I click "Preview in Teams", it shows an error in Teams with these details copied to the clipboard: "Error while reading manifest.json". If I download the app package and "upload a custom app" I get the same error. What can I do to resolve this? If I remove the messaging extension configuration, it works but I configured that part in their app and that's what I want to build.
This is my manifest file:
{
"$schema": "https://developer.microsoft.com/en-us/json-schemas/teams/v1.11/MicrosoftTeams.schema.json",
"version": "1.0.0",
"manifestVersion": "1.11",
"id": "3fXXXX",
"packageName": "com.package.name",
"name": {
"short": "Domo Integration",
"full": ""
},
"developer": {
"name": "Domo Inc.",
"mpnId": "",
"websiteUrl": "https://www.domo.com",
"privacyUrl": "https://www.domo.com/company/privacy-policy",
"termsOfUseUrl": "https://www.domo.com/company/service-terms"
},
"description": {
"short": "short",
"full": "full"
},
"icons": {
"outline": "outline.png",
"color": "color.png"
},
"accentColor": "#FFFFFF",
"composeExtensions": [
{
"botId": "deXXXXXXXX",
"commands": [],
"canUpdateConfiguration": true,
"messageHandlers": [
{
"type": "link",
"value": {
"domains": [
"*.domo.com"
]
}
}
]
}
],
"validDomains": [
"*.domo.com"
]
}

#ccnokes In order to use messaging extension in your bot, you need to provide at least one command. commands is required property in composeExtension - see doc.
I was also getting the same error when tried with your manifest but after adding commands it worked totally fine.
