asn1tools.codecs.ber.DecodeTagError:

[HalaHelmi]

Hi,,

I'm facing a problem while I'm trying to decode multiple cdrs in .ber files. it decode the only the first bunch of cdrs and then gave me this error.

while it works for some other files correctly. asn1tools.codecs.ber.DecodeTagError: ChargingDataOutputRecord: Expected CHOICE(ChargingDataOutputRecord) with tags ['a0', 'a1', 'a2', 'a3', 'a4', 'a5', 'a6'], but got '00'. (At offset: 0)

Thanks in advance.

I have a similar problem. asn1tools.codecs.ber.DecodeTagError when using two "SEQUENCE OF" in "CHOICE" My ASN.1 file:

A DEFINITIONS::=BEGIN
B::=CHOICE{
    c   SEQUENCE OF INTEGER,
    d   SEQUENCE OF IA5String
}
END

My python code:

import asn1tools
asn_file = asn1tools.compile_files('./test.asn',codec='ber')
encoded = asn_file.encode('B', ('c', [1]))
print(hex(int.from_bytes(encoded, byteorder='big')))
decoded = asn_file.decode('B', encoded)
print(decoded)

Output:

The OSS Nokalva playground gives a compile error: line 4 (A): A0100E: Duplicate tag in type B: element 'c' (line 3) and element 'd' (line 4).

asn1tools should probably give an compile error as well, but I guess there is a bug.
