udacimak: Render error: CODE: ERR_INVALID_ARG_TYPE

Describe the bug I am using udacimak 1.4.0 and getting the following error.

2019-05-17T14:49:15.955Z [error]: TYPEERROR [ERR_INVALID_ARG_TYPE]: The "path" argument must be of type string. Received type undefined
CODE: ERR_INVALID_ARG_TYPE

    at process._tickCallback (internal/process/next_tick.js:68:7)

The error is occurring at the time of rendering the course. To download I have used: udacimak download nd041 There was no mistake. To render I used: udacimak render "Fundamentos Web Front-End v2.0.0" When it arrives in the folder Fundamentos Web Front-End v2.0.0\Part 02-Module 01-Lesson 02_Lab - Sintaxe de HTML\08. Construindo links.html the error happens.
