What is the Character Limit of Response that GEN AI provides?

Hi , I want to know the character limit that the Appian Private AI (GEN AI) - Document Extraction.

I've uploaded a document with table value of 43 rows. But in the response , I can get only 30 rows as incomplete.

I have altered the prompt also, but its not the problem. I've searched about the character limit of Extraction , But couldn't able to find it .. 

Can anyone help me with this matter?
