Your WSGIPath refers to a file that does not exist

Solution 1:

There's a lot of configuration issues that can arise with Flask deployed on AWS. I was running into a similar issue as you, so I can at least show you what I did to resolve the WSGI error.

First, apparently you can do this without the .ebextensions folder (see this post here. and look at davetw12's answer. However, be aware that while this works, I'm not entirely sure that davetw12's conclusion about .ebextensions is correct, based on some of the comments below). Instead, (in the Terminal), I navigated to my project at the same level as my .elasticbeanstalk directory and used the command eb config. This will open up a list of options you can set to configure your beanstalk application. Go down through the options until you find the WSGI path. I notice you have yours set to project/application.py, however, this should not include the folder reference, just application.py. Here is how it looks on my Mac in the terminal (WSGI path is near the bottom).

Note that once you get that set, EB will probably redeploy. That's fine. Let it.

Once you get that set, go into your application.py file and make sure you call your app application. For example, mine looks like this:

from flask import Flask
from flask import render_template
application = Flask(__name__)

@application.route('/')
@application.route('/index')
def index():
    return render_template('index.html',
                           title='Home')

This took away the WSGI path error - although I still had to fix some other issues following this :-) But that is a different set of questions.

Solution 2:

If anyone here is doing via AWS Console (GUI), modify the configuration and put your script name in WSGIPath as below.

I'm giving bonus hints if you are newer.

• You should match the script name and the Flask object too.
• Common mistake: When you're compressing the source code, you need to select the files and compress, not the folder. (make sure you have the .py in the root of the zip)

from flask import Flask
application = Flask(__name__)

@application.route("/")
def hello():
    return "Hello"

if __name__ == "__main__":
    application.run()
