Application Error

Hello,
I think a deploy error has occurred in your application.


I think there are three errors which possibly might have occurred or maybe anyone of them.

**Error-1: Error with Procfile:**
->In order to push code to Heroku,we have to create a procfile and without it Heroku might not know how to run this app.
->Often the procfile content is "web:node link-to-the-file-server". Please check the content, there should not be extra space
after colon.
Note:- Extra spaces can cause error while deploying to Heroku.

**Error-2: Missing Dependencies:**
-> If any developer dependencies are used ,then by default Heroku will not install developer dependencies which might show "package not found " error.
-> To install the developer dependencies there is a way that is to change all developer dependencies to dependencies in
package.json file. Then, you also need to commit the change and deploy it again.

**Error-3: Missing Parameters:**
->In localhost you can get all your parameters with the .env file but the problem is that you might have not pushed the .env file to the Heroku.
-> To access all the parameters in .env file,the steps are as follows:
Open the Heroku-->Go to the settings option -->Click on reveal config -->Here push all the .env config
Please do check the parameters of PORT app.
