Attributes forms and problem with setting variables as defaults (QGIS 3.4.1)

Original Redmine Issue: 20379
Affected QGIS version: 3.4.1
Redmine category:forms

I have geopackage layer with two fields: user and data_mod. I'd like to set default value for user field with @user_account_name variable (widget type: Text Edit) and for data_mod field with function now() (widget type: Date/Time). In the first case, after clicking Apply button, this settings aren't save, and the default value changes automatically to 'NULL'. In the second case, default value changes automatically to exact date, not date from variable now().

Works as expected on 2.18 (I'm not sure @user_account_name is available on 2.18)?

• status_id was changed from Open to Feedback

I can't reproduce this. Is it still an issue in 3.16?
