There seems to be an issue for some users with this warning.
CSV files also fail with the same error.
The only workaround is to adapt the file to Koinly format.
Developers are notified about this issue and will be fixing it shortly.

This issue is happening if you added a rule to your Coinbase wallet that remaps all USD to USDC (or any other stablecoin)

The solution is to delete this rule (via Settings -> Rules) and resync the wallet.
