Is there a trick to decoding the "0501..." strings used by SigningType.MICHELINE. I am trying to unpack it from python using:

from pytezos.michelson.types import MichelsonType

ty = MichelsonType.match({'prim': 'string'})

I always get an error that it is the wrong number of bytes though, any thoughts? Do I just need to pass the original length and manually unpack?

pytezos.michelson.micheline.MichelsonRuntimeError: not enough bytes to parse array body, wanted 3291190

There is some inconsistency in the docs here: https://tezostaquito.io/docs/signing#generating-a-signature-with-beacon-sdk

The first padding example is different from the full signing code. I think maybe the full example has the wrong padding for the standards?

    Could you provide the entire string you have problems with (or any random string, just for example), so we can check it?
