No assets used in your trading bot can be found in your real or virtual account. To correct this add your quoted asset or an asset you are trading to your account.
For example, if you have a trading bot that has USDC as the quoted asset and the bot trades ADA, ETH and LTC, you would need to add USDC, ADA, ETH or LTC. If you have other assets in your account that your bot does not use, it will be ignored.
