form.json won't open / "missing a required field" error

form.json needs, at minimum, a title and a fields array (even if empty). Check for a typo'd key or a JSON syntax error (a trailing comma, an unclosed brace) - the Script Editor doesn't validate JSON as you type. A project that fails to load shows an error on Input Form rather than a blank or broken screen.

Autocomplete isn't suggesting anything for a field

Two requirements, both manual:

  1. The field needs an Autocomplete Key set in the Form Editor.
  2. autocomplete.json needs a matching key with at least one value.

Blocks look shifted after regenerating base.pdf

Regenerating base.pdf replaces the canvas at a size you choose - every block keeps its exact old position, so a different page size shifts everything relative to the new canvas. Re-check positions in the Overlay Editor.

I made changes and don't see a save option

The app only surfaces Save when something's actually unsaved - if you don't see it, there's nothing pending to lose.

For scripting-specific issues (a computed value not showing up, a block rendering nothing), see Advanced Authoring's problem list.
