Text To Speech dont play Text Content from EPUB

Greetings guys how are you ??

My app get a text from a epub file thanks to Epubjs, but when iam trying play it to TTS Plugin dont work.
TTS plugin its work beacause I can play text from Api Rest JSON content.
What do you think ??


PD: I’m surely that the content is a string content and the catch error told me “ERR_UNKNOW”
