Can't save images about guest-entries

[edalzell]

I solved this @wallacio, I didn't have the enctype=multipart/form-data set on the form tag, that caused that integrity constraint

[edalzell]

Current version of Guest Entries

[edalzell]

now I'm getting a integrity constraint error:

What would cause that?

[wallacio]

The very same for me, unfortunately.

Guest Entries: 2.3.0
Craft Pro 3.4.24

I have two fields which are of type Asset.
Form fields of the format:

<input type="file" name="fields[participantRouteImage][]" id="participantRouteImage" class="custom-file-input">

Submits fine if no image selected.
