Cloud Code Error Internal Server Error 1 using Mailgun

[greatis]

I use Parse Server on the Google Cloud.
Migration works well.
I am able to read information from my classes, upload files.

1. My cloud hello function works well.
2. I made a simple Cloud.HttpRequest function.
   It works.
3. Mailgun module gives me always "Internal Server Error", code 1 .
   I use this module:
   https://github.com/ParsePlatform/JavaScriptModulesTutorial

Parse.Cloud.define("sendMail", function(request, response) {
var Mailgun = require('/my path/mailgun.js');
Mailgun.initialize('my-domaun,'api-key');
var stext=request.params.text.replace(/\n/g,'\n');

console.log('text: '+stext);

Mailgun.sendEmail({
to: "[email protected]",
from: request.params.fromEmail,
subject: request.params.subject,
text: stext
},{
success: function(httpResponse) {
console.log(httpResponse);
response.success("Email sent!");
},
error: function(httpResponse) {
console.error(httpResponse);
response.error("Uh oh, something went wrong");
}
});
});

1. I cannot find a way to how to debug cloud code.
   There is no saved cloud code log.
   I cannot find the step by step instructions how to store log to file.
   I think it is important to have a simple switch to activate the log.
   Thanks.

Check the logs from the server when this is executed. It should be printing something out if it's hitting an internal server error.

I see no errors on Mailgun server.
Seems like this is my parse server error:
{"code":1,"error":"Internal Server Error"}

[gfosco]

I mean the logs from your parse-server instance. Run it locally and test. Often if the server responds with code 1, the server instance will have logged a stack trace to the console.

[greatis]

But I don't know where to see the logs from cloud code.

did you import mailgun with require('parse-mailgun')? If that's the case, it's not available in cloud code...

[greatis]

I use myMailModule-1.0.0.js
I use the full path in require:
var Mailgun = require('/full path/myMailModule-1.0.0.js ');

It is not clear that this is an issue in Parse Server, as it concerns "third party" JavaScript code that is being pulled into Cloud Code. I recommend adding logs to your myMailModule-1.0.0.js file to see what Mailgun is responding with.

PS: I am aware that myMailModule.js is one of Parse's own JavaScript examples, but it was written with hosted Parse applications in mind.

Fwiw, you need to use a third party Mailgun module such as https://github.com/bojand/mailgun-js (NOT anything Parse specific - Mailgun.initialize(...) will not work anymore)

Then it is easy as this inside your cloud code function:

var mailgun = require('mailgun-js')({apiKey: process.env.MAILGUN_KEY, domain: 'mg.yourapp.com'});

            var mail = {
                from: '[email protected]',
                to: toEmail,
                subject: subject,
                body: '',
                html: htmlBody
            };

            mailgun.messages().send(mail, function (sendError, body) {
                if (error) {
                    inspect(sendError, 'mailgun sendError');
                } else {
                    inspect(body, 'Successfully send RECEIPT email to "' + toEmail + '"');
                }
            });
