!!! When trying to convert HTML to DAISY audio, we are facing error, and the HTML file is not getting converted to DAISY AUDIO.

[SirishaGorasa]

We have few HTML files. We have tried converting them to DAISY but it's not becoming possible. We have tried with dp2 cli of versions 2.1.7 and 2.1.8. DAISY audio files are not getting generated with either of the dp2 clis.

For your information, the scriptlets we have used are

1. html to epub3
2. epub3 to daisy

I am providing the screen shot of the error

Could you suggest a resolution on this, if any, as quick as possible, please?
Awaiting for your response.
