I'm trying to post my app to Heroku for class and it keeps crashing. This is the error code I'm receiving. I'm not exactly sure what's happening, the H10 error is a blanket statement, maybe someone here could shed some light. This is what I'm getting when using heroku logs --tail. Edit: My app works totally fine on my local machine, I'm only getting this error when trying to post to Heroku

Glancing at your log file, you can see that the top of the stack (at the point in which the exception is thrown) points to a parseConnectionString call. As you most likely deduced (since you included this in your title), the line above is a big clue as to what is going on:
MongoParseError: URI malformed, cannot be parsed
This indicates an issue with the connection string you are providing to the mongoose.connect function. Given the code you have shared, this can only be the result of an invalid process.env.MONGODB_URI value or the fallback mongodb://localhost/budget. Depending on how the MongoDB instance was provisioned, I might lean towards checking the value of the environment variable first, but if you are unsure about this, it might be best to first determine which of the two values your application is using (i.e., you could log this).
Overall, the issue appears to be related to the connection string you are using to connect to the MongoDB instance, and not explicitly caused by an issue with your application.

Hello and thank you everyone for helping. My issue was that I was using my Mongo username/password login info in the URI string, instead of my Mongo username/password combination. I'm not sure if that makes any sense but I have it up and running. Thank you again!
