Solve the following python programming problem given the following code:
def csrf(request) : 
    "
    Context processor that provides a CSRF token, or the string 'NOTPROVIDED' if
    it has not been provided by either a view decorator or the middleware
    " 
    def _get_val() : 
        token = get_token (request) 
        if (token is None) : 
            return 'NOTPROVIDED' 
else : 
            return token 
_get_val = lazy (request, str) 
    return { 
        'csrf_token' : _get_val (), 
} 

    
    

    Fix the buggy line: _get_val = lazy (request, str)

#Here is Python code to fix the buggy line: _get_val = lazy (request, str)
