I have an upload field field_documents (for images, if it may be relevant) on a node. When viewing, the field is not required and shown in a collapsible.
Next, I've added a conditional field for field_company, a boolean. When it's checked, the field_documents should not be visible. And vice versa.
When I check my form, the field field_document is not required, but the field widget however is.
If I check field_company, it gets optional, but when I uncheck it, it goes back to required, despite having nowhere defined it should be required.
Make it not required, if the default state is not required.

Found the issue with the help of a colleague.
There was a required conditional state on the field grouping where the field was added.
When I removed it, the widget was no longer required.
Leaving this for future reference.
