Possible deserialization issue

[nemo83]

Hello

quick message to report a possible deserialization issue in apollo.

I currently have a tx built w/ lucid evolution, which needs to be imported and signed by apollo. This is the tx hex bytes.

I'm currently using these versions:

github.com/Salvionied/apollo v1.0.13-0.20250116203813-b1928b7dbead
github.com/blinklabs-io/gouroboros v0.107.1

Code looks like:

[...]
type CustomChainContext struct {
	Base.ChainContext
}

[...]
func NewCustomChainContext() CustomChainContext {
	return CustomChainContext{
		ChainContext: FixedChainContext.InitFixedChainContext(),
	}
}

[...]
txAsString := "tx_bytes_above"
aCtx := NewCustomChainContext()
tx := apollo.New(&aCtx)
tx, err := tx.LoadTxCbor(txAsString)
if err != nil {
	fmt.Println("Error!", err.Error())
}
fmt.Println("Hello World!", tx.Fee)

Thanks in advance, and please let me know if you need anything else!!
