@Ivor Denham-Dyson I have tested this and found the issue is with tabs in one of the channels in the request payload. For a case where you don't need the tabs, you can try without them. Something like below
POST https://graph.microsoft.com/v1.0/teams
Content-Type: application/json
{
"template@odata.bind": "https://graph.microsoft.com/v1.0/teamsTemplates('standard')",
"visibility": "Private",
"displayName": "Sample Engineering Team",
"description": "This is a sample engineering team, used to showcase the range of properties supported by this API",
"channels": [
{
"displayName": "Announcements ๐ข",
"isFavoriteByDefault": true,
"description": "This is a sample announcements channel that is favorited by default. Use this channel to make important team, product, and service announcements."
},
{
"displayName": "Training ๐๏ธ",
"isFavoriteByDefault": true,
"description": "This is a sample training channel, that is favorited by default, and contains an example of pinned website and YouTube tabs.",
"tabs": [ ]
},
{
"displayName": "Planning ๐
",
"description": "This is a sample of a channel that is not favorited by default, these channels will appear in the more channels overflow menu.",
"isFavoriteByDefault": false
},
{
"displayName": "Issues and Feedback ๐",
"description": "This is a sample of a channel that is not favorited by default, these channels will appear in the more channels overflow menu."
}

As for the error when creating with channel that has tabs, I will get back with I find.
