first_name content length error

Hi,
I am trying to connect FB lead ads and create a workflow.
FB connection is all done and I got the response data, but in the next step "Choose Your Next Application : Action" I am selecting the "Eductrl" App and mapping the fields and while saving I am getting "first_name content length exceeded" error. In our App "EduCtrl" we have kept first_name 50 characters.

Here is the workflow link:

Hello @Erudite,

The EduCtrl app is a user application developed by their team. We recommend reaching out to the EduCtrl team directly, as they would be better positioned to assist you with this issue regarding the first_name content length exceeded error.

Hello @Erudite,

We have made some changes on our end, and the character limit issue now appears to be resolved. Please refer to the attached image for more details.
