Problem scenario
You are trying to pass a string parameter to a Flask application via a call to a URL. You get the message "LookupError: the converter 'str' does not exist." What should you do?
Solution
Use the term "string" instead of "str".
Here is an example of incorrect syntax:@app.route("/ccc/", strict_slashes=False)
This shows the correct syntax:@app.route("/ccc/", strict_slashes=False)
