Runtime Error

What This Error Means

This error occurs when the Jinja2 templating engine in Python is unable to render a template because of a mismatch in the type of a parameter. In this case, the 'path' parameter is expected to be a string, but it's being passed as an integer.

Why It Happens

This error typically happens when there's a typo in the function call or when the type of a variable is not what's expected. In this scenario, the 'path' parameter might be coming from a database query or user input, which could be causing the type mismatch.

How to Fix It

1. 1To fix this error, you need to ensure that the 'path' parameter is a string by using the str() function or by using a string literal. For example:
2. 2// Before (broken code)
3. 3render('home.html', path=42)
4. 4// After (fixed code)
5. 5render('home.html', path=str(42))

Example Code Solution

template = Jinja2Environment().from_string('{{ path }}')
print(template.render(path=42))

template = Jinja2Environment().from_string('{{ path }}')
print(template.render(path=str(42)))
