Side note: When posting code here, enclose the code between lines of three backtick - ` characters. This means you’ll have a line of ```, then your code, then another line of ```. This forces the forum software to keep your code properly formatted.

Those aren’t standard Python error messages.

Please provide additional details about exactly how and where you’re seeing these messages.

Also, what is this formsetify package? Your package or a generally-available third-party package? What is this render_form tag?
