Only allow specific file types using validation rules

Bugs & Issues
1

Am I missing something?

[Step 1 Source Document].Files.Filter(
  Find([Content Type], "pdf") < 0 and
    StartsWith([Content Type], "image/") = false
).Count() = 0

This is always blocking any new submission.

It seems like validation rules do not work for images on create. I suspect it is because they are attached after the entity is created? Not sure.

Changing this to a bug, if others have an idea, do let me know!

It’s a bug, thanks for reporting.

We will fix it. Will inform here when fixed.

By the way how do you create entity with the file? Automations, Forms, somewhere else?

Thank you!!

Forms. Internal form view + form popup. Didn’t try elsewhere.

Hey! Is there any update on this one? Thank you!

I want to implement file compressing, but the compressor can only handle certain file types…

No. We haven’t heard a lot of complaints, so it’s not high-priority I’m afraid

Okay thanks for letting me know! I’ll figure out a different solution in the mean time then
