Error code 1 encountered an internal error while trying to execute a task

Currently, I have this job set up to clear out unnecessary records. The code provided has been simplified for debugging purposes. However, almost 80% of the time when running it, it fails to find anything due to Error code 1 "internal error":

Parse.Cloud.job('cleanStories', function(request, status) {

  Parse.Cloud.useMasterKey();
  var counter = 0;

  var query = new Parse.Query('Story');
  query.doesNotExist("username");
  query.limit(1000);

  query.find({
    success: function(results) {
      counter += results.length;
      status.success(counter + " stories found.");
    },
    error: function(error) {
      status.error(counter + " stories found. Error: " + error.code + " " + error.message);
    }
  });
});

Currently, I have around 568k records. Initially, there were close to 800k records before I began running this job to clear them out. While it used to work fine, now it's consistently showing errors. What could be the issue here?

EDIT:

I've reduced the limit to 50 and noticed a higher success rate in execution. Even with the default limit of 100, it still fails frequently. Is there a way I can increase the limit back to 1000 to speed up processing through the remaining records?

Answer №1

This approach is based on the concept that implementing smaller limits could potentially address timeout issues (assuming it is a per query timeout rather than a per job timeout). Here's a method to execute a large find operation using limit and skip:

function fetchResults(query, results) {
    results = results || [];
    query.skip(results.length);
    return query.find().then(function(findResults) {
        results = results.concat(findResults);
        return (findResults.length === 0)? results : fetchResults(query, results);
    });
}

// To utilize this method, create a query 
var query = new Parse.Query("MyClass");
// Refine the query according to your requirements
// Specify a limit up to 1000, but it's recommended to keep it small
query.limit(20);
var results = [];
fetchResults(query, results).then(function(r) {
    console.log("Total rows found: " + r.length);
    // The variable 'r' will hold all rows matching the query, fetched in batches of 20
});
