Having trouble deleting PFFile in Parse using opensource parse-server

Question

I have a collection that has references to images, and when the user updates that collection with new images, I want to delete the old images. I am keeping references to the URL for the old images to pass into a function that is written in the cloud code.

I am running all of this local on my computer, however I get the same issue when I run this with the server running on Heroku. This is being called from the iOS SDK.

Here is the function in question:

Parse.Cloud.define('removeOldFilesFromDB', function (request, response) {

    var fileUrls = request.params.fileUrls;
    var promises = [];

    for (var a = 0; a < fileUrls.length; a++) {

        promises.push(Parse.Cloud.httpRequest({
            method: 'DELETE',
            url: fileUrls[a],
            headers: {
                'X-Parse-Application-Id': process.env.APP_ID || 'myAppId',
                'X-Parse-Master-Key': process.env.MASTER_KEY || 'myMasterKey'
            }
        }));

    }

    Parse.Promise.when(promises).then( function (result) {
        console.log("Successfully deleted files");
        response.success(result);
    }, function(a,b,c,d,e) {
        console.log("Nope jacked it up!");
        response.error("Error deleting files");
    });

})

When I call the code in question, I don't even see the DELETE request in the parse-server logs at all.

I have the verbose: true flag set in my config, and this is the verbose output to the logs that I get when making this call from the client:

verbose: POST /parse/functions/removeOldFilesFromDB { host: 'e0ae0682.ngrok.io',

    "http://e0ae0682.ngrok.io/parse/files/myAppId/7b5b50e2871af27971be0425f367ab96_file.bin",
    "http://e0ae0682.ngrok.io/parse/files/myAppId/cff909602b60b15331b1ac60a4f08697_file.bin"
  ]
}

Nope jacked it up!
verbose: error: code=141, message=Error deleting files

So it's odd that the DELETE call is not even showing up in there. Am I calling it wrong with the Parse.Cloud.httpRequest method or something?

If I hit the values for fileUrl in my browser, it downloads the images I'm trying to delete so the path is correct.

This is on the latest released version of parse-server, 2.2.10.

These were the instructions that I was following thinking that this is the correct way to do this:

https://parse.com/docs/rest/guide/#files-deleting-files

And this here to make the rest call from the cloud code:

https://parse.com/questions/making-a-rest-call-from-within-cloud-code

According to that, it says I can use Parse.Cloud.httpRequest to make REST calls, so I am not sure what you are referring to as that not the correct ways. Both of those have links to the docs and that is what I followed.

So I am obviously doing something wrong but I am not sure, anyone able to help out?

Answer 1

Just remove myAppId from file URL.

(eg)

from

http://e0ae0682.ngrok.io/parse/files /myAppId /7b5b50e2871af27971be0425f367ab96_file.bin

to

http://e0ae0682.ngrok.io/parse/files/7b5b50e2871af27971be0425f367ab96_file.bin
