Using Parse Cloud Functions with Mailgun, my email code hits a ‘Cannot call method get of undefined’ error. How can this be fixed?
Parse.Cloud.define('dispatchMail', function(req, cb) {
var mgClient = require('mailgun-js')({ domain: 'example.org', apiKey: 'newSecretKey' });
mgClient.messages().send({
to: req.params.recipient,
from: '[email protected]',
subject: req.params.title,
text: req.params.content
}, function(err, res) {
if (err) cb.error('Email error'); else cb.success(res);
});
});
hey, check if req.params is defined and includes the right keys. sometimes missing paramaers cause undefined errors inside the mailgun library. double-checking and adding logs might help pinpoint where get() is being called on nothing.
hey, try console.log(req.params) before calling mailgun. i faced a simmilar prob when some data wasn’t passed correctly. check every param and see if any mispelled or missing. might help you get to the root of the issue.
Based on my experience, the error typically indicates that one of the objects or properties expected by the Mailgun library is not available at runtime. It is crucial to ensure that all parameters are defined and correctly passed to the Cloud function. I encountered something similar when a key was misspelled in the request payload and it led to an issue deep in the library. Using console.log to output the entire req.params object before the call helped me catch missing or misnamed properties. Consider checking the order of asynchronous calls as well if you are dynamically modifying parameters.
I have encountered a similar issue during my development process. In my case, the problem was not solely with the missing parameter but rather with how previous functions were modifying the request object before reaching the email dispatch call. In one instance, a middleware inadvertently removed or replaced properties, resulting in the Mailgun code receiving undefined values. I solved it by ensuring that the request object remained intact throughout all processing stages and by adding detailed logging at different steps to trace the evolution of req.params. Reviewing the entire data flow was crucial in identifying the root cause.
