Cannot use " in body for scheduling

[BenRomberg]

This is a Bug Report

Description

With the following schedule configuration:

      - schedule:
          rate: rate(1 minute)
          enabled: true
          input:
            path: /switch
            httpMethod: POST
            headers:
              Content-Type: application/json
            queryStringParameters: {}
            body: '{ "functionId": "..." }'

I get the following exception:

SyntaxError: Unexpected token f
    at Object.parse (native)
    at /usr/local/lib/node_modules/serverless/lib/plugins/aws/deploy/compile/events/schedule/index.js:123:41
    at Array.forEach (native)
    at /usr/local/lib/node_modules/serverless/lib/plugins/aws/deploy/compile/events/schedule/index.js:21:28

The f comes from the functionId in the body. If I remove the f, the error becomes Unexpected token u (from "unctionId").

Looking at the code, the problem is with escaping the input in lib/plugins/aws/deploy/compile/events/schedule/index.js in the variable scheduleTemplate. The quotes in the body get transformed to \" in Input, and then to \\" in scheduleTemplate. Note the missing backslash - only the original backslack gets escaped, not the quotes.

I was able to hack a quick fix together and it works (not suggesting as a fix, just to illustrate that this would fix it). The original scheduleTemplate was renamed to scheduleTemplate2 before:

const scheduleTemplate = scheduleTemplate2.replace(/\\\\"/g, '\\\\\\"');
