Merging ASN.1 files

[MartijnHarmenzon]

I am trying to merge these files:
https://forge.etsi.org/rep/ITS/asn1/cdd_ts102894_2/-/blob/release2/ETSI-ITS-CDD.asn
https://standards.iso.org/iso/ts/19091/ed-2/en/ISO-TS-19091-addgrp-C-2018.asn
https://forge.etsi.org/rep/ITS/asn1/is_ts103301/-/blob/v1.3.1/SPATEM-PDU-Descriptions.asn

But getting the error:

yasn1.error.PyAsn1Error: <TagSet object, tags 64:0:9> not in asn1Spec: None

This is my code:

from pyasn1.codec.ber import decoder, encoder
from pyasn1.type import univ


if __name__ == "__main__":
    with open("ETSI/ITS-Container.asn", "r") as module1_file:
        module1 = module1_file.read()

    with open("ETSI/ISO-TS-19091-addgrp-C-2018.asn", "r") as module2_file:
        module2 = module2_file.read()

    with open("ETSI/SPATEM-PDU-Descriptions.asn", "r") as module3_file:
        module3 = module3_file.read()

    # Decode the contents of the files into ASN.1 objects
    module1_obj, _ = decoder.decode(module1.encode())
    module2_obj, _ = decoder.decode(module2.encode())
    module3_obj, _ = decoder.decode(module3.encode())

    # Concatenate the contents of the objects into a single sequence
    merged_module_obj = univ.Sequence(module1_obj + module2_obj + module3_obj)

    # Encode the merged object back into a BER-encoded string
    merged_module = bytes(encoder.encode(merged_module_obj))

    # Write the merged module to a file
    with open("merged_module.asn", "wb") as merged_module_file:
        merged_module_file.write(merged_module)

Help is much appreciated.
