💡 Hint

Common Mistakes

Putting full call in blank causing syntax error

Using wrong status code

You must call abort with the status code as an argument like abort(400). But since the code already has (400) in the code, the blank is only for the function name abort.

4fill in blank

hard

Fill both blanks to abort with a 500 Internal Server Error and import the correct function.

Flask

from flask import Flask, [1]
app = Flask(__name__)

@app.route('/error')
def error():
    [2](500)
    return 'This will not run'

Drag options to blanks, or click blank then click option'
