Impossibility to retrieve and prove KV data with nil values
Due to a bug in the ICS23 package, it’s currently not possible to query anil
or empty value from a remote chain. If your KV query is registered with a key K
and the value under this key is nil
or empty, the submission of such a KV result will fail due to an IAVL-proof verification error:
nil
or empty value. This results in the error:
nil
or empty values.
