I recently upgraded to v4.4.5.21. I have a rule which requires an attachment if Field1 = X or Y. This rule has been functioning for months prior to the upgrade, but is no longer recognizing when an attachment has been added. Instead, I get the “must specify a value…” validation text as shown in the attached screenshot. I’m not seeing any errors in Dev Tools. The form saves without issue when I disable the rule.
Thanks for the feedback – I have confirmed this bug occurring in NewForm and will publish an updated version within a few days to fix it.
The issue was introduced in SPJS-utility.js v1.350 / DFFS v4.4.5.17 on February 21, 2021 so downgrading to a version prior to that will fix it while you wait for an update.
