我正在嘗試創(chuàng)建一個(gè)連接到 lambda 的 API 網(wǎng)關(guān)，它使用 handlebars 解析 HTML 模板，然后返回它，但是當(dāng)我在本地運(yùn)行它時(shí)，甚至在使用 AWS 的測(cè)試 url 上運(yùn)行時(shí)，我都收到了這個(gè)錯(cuò)誤。{"errorMessage": "invalid character 'e' looking for beginning of value","errorType": "SyntaxError"}這是我的 SAM 模板AWSTemplateFormatVersion: "2010-09-09"Transform: AWS::Serverless-2016-10-31Description: data-template-rendererParameters:  Stage:    Type: String    AllowedValues:    - dev    - staging    - production    Description: environment valuesResources:  # Defining the API Resource here means we can define the stage name rather than  # always being forced to have staging/prod.
