CandidType from candid <0.10 is not the same / compatible with CandidType from candid >= 0.10. I suspect this is where the problem comes from. You can check with cargo tree which crate uses which candid version. Solutions would be to either downgrade everything to 0.9 or to use the sdk repo on a current commit instead of the (very old) published version
