Unable edit submissions online

Greetings to all. We made a small change to the form today after several uploads, and as a result of the changes we were unable to edit the submission online.
Thanks a lot

Welcome to the community, @ahmedyandoma! Could you also let us know the server you are using? In addition, could you also share with us a screenshot of the issue you get when you try to edit your submissions? These details should help the community to troubleshoot your issue.

@Kal_Lam I am using a kobohumanitarian server (Usename: xxxxxxx)
form title: KATSINA STATE DAILY COMMUNITY BIRTH & STILL BIRTH REGISTER
below is the error screenshot as requested

@ahmedyandoma, so here is your issue:

In the pull-data syntax, you have used the CSV filename as book, while your actual CSV file name is Book.

You will need to have both names the same to avoid this issue.
