bug: chunk fetching error (unrecognized concrete type full name tm.StorageDepositEvent)

[matijamarjanovic]

We have started experiencing this error for certain transactions used to setup Volos development mode. The exact transactions executed are: full-workflow and multi-ops-workflow (from these files: https://github.com/stefann-01/gno/blob/feat/gnolend/volos-tests/test.mk and https://github.com/stefann-01/gno/blob/feat/gnolend/volos-tests/test.mk (in that order)).

Here are some error logs:
