我正在尝试使用 Gmail 插件访问 Gmail 中的所有草稿，但它会记录这样的错误 Access denied: : Missing access token for per message scope authorization. [line: 8, function: buildAddon, file: Code]

我的 onTrigger 函数看起来像这样

function buildAddon(e) {
var cards = [];
var accessToken = e.messageMetadata.accessToken;
GmailApp.setCurrentMessageAccessToken(accessToken);

var draftMessages = GmailApp.getDraftMessages();
for (var i = 0; i < draftMessages.length; i++) {
    cards.push(CardService.newCardBuilder()
        .setHeader(CardService.newCardHeader()
            .setTitle(draftMessages[i].getBody())).build());
}
return cards;
}

清单json文件看起来像这样

{
"oauthScopes": [        
    "https://www.googleapis.com/auth/gmail.readonly",      
    "https://www.googleapis.com/auth/gmail.addons.execute",

您缺少草稿权限的范围。

“<a href="https://www.googleapis.com/auth/gmail.compose" rel="nofollow noreferrer">https://www.googleapis.com/auth/gmail.compose 管理草稿和发送电子邮件” </p>

这是范围的参考： https ://developers.google.com/identity/protocols/googlescopes#gmailv1
