What might be the cause of this error?
b"Failed to unmarshal C1 json file : encoding/hex: invalid byte: U+0058 ‘X’
I am doing /cmd/smartcontract/main.go build of a Contract Offer but thru a command shell opened from python 3. Before, it always worked when I did it manually from the smartcontract CLI.
So I suppose here I am sending the wrong encoding from python (?)
I was NOT having this error all these last few months so it is something I did recently.
