Conditional logic doesn't work on FileUpload field

[Afsaneh1987]

Hello

I have created a form with two fields:
1- Check box
2- File Upload
I want to use conditional logic in the FileUpload field. The conditional logic looks like this:
If Checkbox is equal to checked then
hide FileUpload
Unfortunately, the conditional logic doesn't work properly. I checked this in the DevTools and I realized that the FileUpload does not have a "data-sc-field-key".
If I manually add the attribute to this, it starts working.
I am currently using Sitecore 9.1

Could you please suggest me to resolve this problem?

Thanks.
