Your final-form code is working fine. The problem I think lies with TextAreaAutosize, since it doesn't know how to pass data directly to your form. So you might need to add a handler on that field for the onChange event.

Based on the final form documentation, this code sample below seems to work just fine:sandbox-code Just checkout the second attempt section.
