I was able to claim the P2S box (it was quite straightforward as no additional information was required to spend the box, since the script already evaluates to true).
However, I’m having trouble spending the P2SH box. My script matches the expected blake2b-256 hash. But I get the following error:
Malformed transaction: Scripts of all transaction inputs should pass verification. 6ab7e2e0d8bb2c62b2209c80dec88227f6af83f6ccfdb61ff3df864933e1acca: #1 => Failure(org.ergoplatform.validation.ValidationException: Validation failed on ValidationRule(1000,Deserialized script should have expected type) with args WrappedArray(DeserializeContext(1,SSigmaProp), ConstantNode(Coll(-1),Coll[SInt$])))
It’s possible I’m not serialising the context variable correctly and I’m missing some kind of wrapper. Or perhaps there’s a bug in the P2SH contract?
