"End of scene 1 does not align with script (HTTP Status Code: 400)"

variable placeholder on my script is "{{script}}" on my template.
I am repalcing this placeholder with 20-30 second speech, and recieving error message when using zapier.

manually inputting this script (20-30 second long) into heygen and manually submitting for production proceeds to give warning of:

"Notice before you submit
These issues may affect the final outcome of the generated video. It is recommended to update your video before submission.
Overall scene duration exceeds overall script duration.
The scene exceeding the script duration will not have TTS (text-to-speech) audio. If there is an Avatar in this part of the scene, it will not speak."

If i set my avatar length in template from 2 seconds to 50 seconds, still does not produce.

Can you someone please help decode. If we can implement dynamic template length per script i think this would work?
