Unexpected token '<', " <html> <h"... is not valid JSON
I sussed it I just imported the pdf, I tried that originally but it only imported the first 2000 words for some reason.
Sounds like some coding issue with the text you are copy-pasting. Can you check if there are some '<', " <html> <h" codes in the text and remove them before saving a lesson?
No codes I checked for all '<' and '>' symbols in the text and still getting the same error message.
Please let me know if you are still experiencing the same issue now.
If yes, please send me that file so that I can test on my end.
