Formidable V2 Filter issue about formidable

[GrosSacASac]

Behaves like Array.filter: Returning false will simply ignore the file and go to the next.

use form.emit('error') inside filter to make form.parse error (formData.emit('error') in your case)

I also recommend you to slugify ext as it is user input and may contain invalid characters

                    return `resume_${currentTimeStamp}${slugify(ext)}`;
