no required module provides package cosmossdk.io/core/appconfig; to add it:

type func(x *descriptorpb.FileDescriptorProto, y *descriptorpb.FileDescriptorProto) int of (func(x, y *descriptorpb.FileDescriptorProto) int literal) does not match inferred type func(a *descriptorpb.FileDescriptorProto, b *descriptorpb.FileDescriptorProto) bool for func(a E, b E) bool

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 DeleteVersion)

undefined: iavl.NewMutableTreeWithOpts

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 DeleteVersion)

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/cosmos/ics23/go".CommitmentProof) as *"github.com/confio/ics23/go".CommitmentProof value in assignment
