解析云代码未执行指定任务，并且未创建日志

Question

my afterSave cloud code should run after each save, but i don't see it performing the task. also no debug info is written to a local "temp.txt" file

My parse server is running on docker container (maybe it's relevant) I did a do a clean docker run (to launch the parse server) after the main.js was created in the /parse-server/cloud subfolder , but still not seeing anything

how can i debug this cloud-code issue ?

my main.js content:

Parse.Cloud.afterSave("Post", (request) => {
var fs = require("fs");
    const image = request.object.get("image").url();
    const detail  = request.object.get("detail");
    const geo = request.object.get("geo");
    const itemId = request.object.get("objectId");
fs.writeFileSync('./temp.txt', request, function(err, data) {
  if (err) console.log(err);
});

    console.log(detail);
    console.log(image);
    console.log(geo);
    console.log('========');

var data =detail+" "+image+" "+geo+" "+request;

fs.appendFileSync("./temp.txt", data, function(err, data) {
  if (err) console.log(err);
  console.log("Successfully Written to File.");
});

    var postRequest = require('request');
    postRequest({
      method: 'POST',
      preambleCRLF: true,
      postambleCRLF: true,
      json: true,
      uri: 'https://graph.facebook.com/1111/feed?access_token=sometoken',
      body:
        {
          message: detail,
          link: image
        }
    },
    function (error, response, body) {
      if (error) {
        return console.error('upload failed:', error);
        console.log('statusCode:', response && response.statusCode);
        fs.appendFileSync("temp.txt", response+" "+ response.statusCode
                ,function(err, data) {
                       if (err) console.log(err);
                });
      }
      console.log('Upload successful!  Server responded with:', body);
    })

  }
);

when launching parse docker container (using "docker run" for example) we must also pass " The absolute path to our cloud code main.js file." (including the main.js)

for example:

sudo docker run  --name parse --network=test  --appId <app-id> --masterKey <mater-key>--publicServerURL https://my-url.com/parse --databaseURI mongodb://mongo:port/mongo --cloud /parse-server/<cloudpath>/main.js 

the missing switch inside the " docker run " command here was:

--cloud /parse-server/cloudpath/main.js

this resolved the issue
