我正在尝试使用 Gmail 插件访问 Gmail 中的所有草稿，但它会记录如下错误Access denied: : Missing access token for per message scope authorization. [line: 8, function: buildAddon, file: Code]
我的 onTrigger 函数如下所示
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;
}
和清单json文件看起来像这样

您缺少草稿权限的范围。
“https://www.googleapis.com/auth/gmail.compose https://www.googleapis.com/auth/gmail.compose管理草稿并发送电子邮件”
以下是范围的参考：https://developers.google.com/identity/protocols/googlescopes#gmailv1 https://developers.google.com/identity/protocols/googlescopes#gmailv1
