as a workaround you can add this line of code before if (is_numeric($action)) {:

if (!is_array($data)) continue;

[manuel-84]

there have been some releases since I've opened this issue but it is still unfixed

Having the naked 'captcha' in the process section seems to be the issue. Here is my fix:

    process:
        - captcha:
            dummy: dummy

Same issue suddenly (Grav 1.7.23, Form v5.1.2).

workaround suggested seems to be working as well.

I have added if (!is_array($data)) continue; in user/plugins/form/classes/Form.php line 925
