Cassandra AssertionError: length is not > 0

Running into the following exception trying to start my 3.0.5 cassandra cluster. Not sure what this means or how to proceed.

INFO  14:14:05 Initializing keyspace.table

Your one table looks to have a corrupted metadata component. Try running sstablescrub (https://docs.datastax.com/en/cassandra/2.2/cassandra/tools/toolsSSTableScrub.html) on the sstables in the affected table and remove the offending one. You should only need to run the manifest check (--manifest-check option) since thats whats actually failing in your stacktrace. Once node starts up again be sure to run a repair on it to restore any lost data.
