Non-helpful error prompt for listing items on Storefront

I am trying to list an NFT from a test contract via the following tutorial:

However, listing the NFT transaction for non-dapper users for testing via FLOW SDK& cadence gives the following unhelpful error:

expected `Capability<&AnyResource{NonFungibleToken.Provider, NonFungibleToken.CollectionPublic}>`, got `Capability<&AnyResource{NonFungibleToken.Provider, NonFungibleToken.CollectionPublic}>

Here is the transaction on testnet:

Storages for the account are set up successfully and according to the technical tutorial.

Since the “expected” and “got” section of the error message is the same, it is tough to debug and pinpoint the issue. Any help is appreciated.
