What are the limitations of the media type text for the mediatopic.post method?

Question

Classmates

I did not find any restrictions on the number of characters for the text parameters of the mediatopic.post method anywhere in the documentation. I'm personally interested in the restrictions on media type text.
What is the maximum length of the text published through this method?

Answer 2
