Description
Hello,
I encountered a ASN1BERDecodeErr error while parsing RetrieveNotificationsListResponse in GSMA SGP.22 v3. The error can also be reproduced in asn1_play (https://amenitypj.in/asn1Play) with other releases of SGP.22
Steps to reproduce:
git clone https://github.com/pycrate-org/pycrate
cd pycrate
tools\pycrate_asn1compile.py -i c:\test\SGP.22-v3.0-1\RSPDefinition.asn c:\test\SGP.22-v3.0-1\PKIX1Implicit88.asn c:\test\SGP.22-v3.0-1\PKIX1Explicit88.asn c:\test\SGP.22-v3.0-1\PEDefinitions.asn -o c:\test\SGP.22-v3.0-1\gsma_sgp22_v3
