AttributeError: 'NotFound' object has no attribute 'encode'

When a user goes on my flask app with a URL that has more than 3 sub paths, like "domain.com/var1/var2/var3/var4", it throws the error below:

Traceback (most recent call last):
File "/usr/local/lib/python2.7/site-packages/flask/app.py", line 1836, in __call__

It works fine for url's that have less than or equal to 3 subpaths like "domain.com/var1/var2/var3", but I have routes for url's with 1, 2, and 3 subpaths.

How can I get my app to go to the 404 Page Not Found method instead of throwing this error?

Thank you!

edit.. Here's a pastebin of the route methods I'm using. http://pastebin.com/kjYsqk9n

Sorry I can't provide an example of this problem, it's really weird and I don't know how to reproduce it myself. My other flask apps work fine, this one doesn't. If anyone needs clarification, please let me know... thanks for all your help!

Solution

  • Found out why it was returning that error. It turns out I was passing in the error object instead of "404" at the end of this line: 

    return render_template("error.html", usa=usa, canada=canada, breadcrumbs=breadcrumbs, error_code=e), 404

    Thanks!
