I am also getting same error. By doing this:

pdfDoc
    .encrypt({
        password: '123',
        ownerPassword: '123',
        userProtectionFlag: 4
    })
    .endPDF();

error is gone but encryption is not working.

As a workaround you can add ts-ignore.

pdfDoc
    .encrypt({
        //  @ts-ignore
        userPassword: '123',
        ownerPassword: '123',
        userProtectionFlag: 4
    })
    .endPDF();
