setReadOnly method doesn't seem to work

[alaa-ismail]

Hello,

I'm trying to use the SDK to create read-only fields. I've tried multiple ways but none seem to work. The field always ends up being editable. Below is the code I'm using

const doc = new Document()
doc.appendFile(new File({ name: 'page1', fileId: 'FILE_ID' }))
doc.appendFile(new File({ name: 'page2', fileId: 'FILE_ID' }))
const field = new TextField()
field.setFileIndex(0)
field.setReadOnly(true)
doc.appendFormField(field)

Looking at the source code, I also tried field.setReadOnly({readOnly: 1}) but that didn't work either.

Can you please advise on how to make fields read-only?

I figured out the cause of the issue. I needed to have field.setSigner("OWNER") to make it read-only.
