In your program you use page.insert_textbox but you do not check the return code of this method!
As documented, insertion will be refused if the text won't fit into the rectangle. This situation is indicated by a negative return code.

Other comments:

1. Your PDF receiving the translated text is new. You do never need to use page.clean_contents() for new pages.
2. If you do not want to be bothered by space problems, why don't you use page.insert_htmlbox() instead? It has a similar call pattern but will auto-shrink text if it doesn't fit at zoom = 100%. There are many more advantages beyond this.
