Null reference exception when encoding SET OF INTEGER #3
Description
Trying to encode this ASN.1 sequence
AuthorizationList ::= SEQUENCE {
purpose [1] SET OF INTEGER OPTIONAL,
algorithm [2] INTEGER OPTIONAL,
keySize [3] INTEGER OPTIONAL,
digest [5] SET OF INTEGER OPTIONAL,
ecCurve [10] INTEGER OPTIONAL,
noAuthRequired [503] NULL OPTIONAL,
creationDateTime [701] INTEGER OPTIONAL,
origin [702] INTEGER OPTIONAL,
rootOfTrust [704] RootOfTrust OPTIONAL,
osVersion [705] INTEGER OPTIONAL,
osPatchLevel [706] INTEGER OPTIONAL,
attestationApplicationId [709] OCTET STRING OPTIONAL,
attestationIdSerial [713] OCTET STRING OPTIONAL,
vendorPatchLevel [718] INTEGER OPTIONAL,
bootPatchLevel [719] INTEGER OPTIONAL
}
I used the compiler to turn that into this class

When I was trying to figure it out myself I debugged the project and saw that the null reference exception was happening on this line when trying to encode the Digest field.
I'm sure I'm just missing something small, but I would really appreciate some help or advice. Thanks!
