substrate-relay v1.5.0 error

[serban300]

Stumbled upon this while running the manual P<>K asset transfer test. It happens only on substrate-relay v1.5.0. v1.4.0 works correctly

Oh sorry, maybe Polkadot and Kusama will need to be updated to the latest version. Closing this for the moment.

Well, we will need to release a new version of Polkadot <> Kusama bridge soon (before P/K runtimes will be updated with those _free_headers_interval methods, I hope) and we will probably will be doing that from the same master branch (though I'm not sure yet). So better have it fixed
