cannot use (*immutableTree)(nil) (value of type *immutableTree) as Tree value in variable declaration: *immutableTree does not implement Tree (wrong type for method Hash)

cannot use (*iavl.MutableTree)(nil) (value of type *"github.com/cosmos/iavl".MutableTree) as Tree value in variable declaration: *"github.com/cosmos/iavl".MutableTree does not implement Tree (missing method DeleteVersionsTo)

assignment mismatch: 1 variable but iavl.NewMutableTree returns 2 values

too many arguments in call to iavl.NewMutableTree

undefined: iavl.InitialVersionOption

cannot use tree (variable of type *"github.com/cosmos/iavl".MutableTree) as Tree value in struct literal: *"github.com/cosmos/iavl".MutableTree does not implement Tree (missing method DeleteVersionsTo)

cannot use &immutableTree{…} (value of type *immutableTree) as Tree value in struct literal: *immutableTree does not implement Tree (wrong type for method Hash)

impossible type assertion: istore.tree.(*immutableTree)

impossible type assertion: st.tree.(*iavl.MutableTree)

cannot use tree.GetMembershipProof(key) (value of type *"github.com/confio/ics23/go".CommitmentProof) as *"github.com/cosmos/ics23/go".CommitmentProof value in assignment
