When I use Create a group channel api I get "Channe not found" error message

export async function createChannel(body) {
return await sendbirdApiCall({
method: ‘POST’,
endpoint: ‘/group_channels’,
body: {
is_public: true,
is_distinct: false,
custom_type: ‘new’,
name: Default - ${body.email},
user_ids: [botUserId, body.userId],
operator_ids: [botUserId, body.userId]
}
});

{“message”:“"Channel" not found.”,“code”:400201,“error”:true}
