Why consistent errors help developers in Rest API - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to return a 404 error when a resource is not found.

Rest API

if resource is None:
    return [1](404, 'Resource not found')

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

💡 Hint

Common Mistakes

Using print instead of abort does not send an HTTP error.

Using raise without an exception class will cause a syntax error.

Using abort with a 404 status code sends a consistent error response to the client.

2fill in blank

medium

Complete the code to return a JSON error message with status 400.

Rest API

return [1]({'error': 'Bad request'}), 400

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

💡 Hint

Common Mistakes

Using json returns a string, not a response object.

Using print does not send a response to the client.

jsonify formats the dictionary as JSON and sets the correct headers.

3fill in blank

hard

Fix the error in the code to send a consistent 500 error response.

Rest API

try:
    process_request()
except Exception as e:
    return [1]({'error': str(e)}), 500

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

💡 Hint

Common Mistakes

Using print does not send a response to the client.

Using abort without a message does not include error details.

Using jsonify ensures the error message is sent as JSON with the correct status code.

4fill in blank

hard

Fill both blanks to create a consistent error handler for 403 Forbidden errors.

Rest API

@app.errorhandler([1])
def forbidden_error(error):
    return [2]({'error': 'Forbidden'}), 403

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

A403

Bjsonify

C404

Dabort

💡 Hint

Common Mistakes

Using 404 instead of 403 changes the error meaning.

Using abort inside the handler can cause recursion.

The decorator uses the 403 status code, and jsonify sends the JSON error response.

5fill in blank

hard

Fill all three blanks to create a consistent error response with a custom message and status code.

Rest API

def error_response(message, code):
    response = [1]({'error': message})
    response.status_code = [2]
    return response

return error_response([3], 401)

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

Ajsonify

B401

C'Unauthorized access'

Dabort

💡 Hint

Common Mistakes

Setting status_code to a string instead of an integer.

Passing the message without quotes causes a syntax error.

jsonify creates the JSON response, 401 sets the status code, and the message is a string describing the error.
