# Troubleshooting

> Having trouble? Start here

### WagmiProviderNotFoundError: `useConfig` must be used within `WagmiProvider`

This issue is usually the result of multiple wagmi versions, make sure you only have 1 version of wagmi installed. You may also want to delete and reinstall your node modules and clear all caches.

### No QueryClient set, use QueryClientProvider to set one

If you've set the QueryClientProvider with a QueryClient it could be that you have multiple versions of tanstack/react-query installed. Make sure to double check and reduce this to just a single version of the package. You may also want to delete and reinstall your node modules and clear all caches.

### The UI looks unstyled

Make sure you've imported the ui package styles:

```typescript theme={null}
import '@relayprotocol/relay-kit-ui/styles.css'
```

If the issue persists make sure there's no reset css or other css file overriding the styles provided by the package.

### Incompatibility

If you see an error message that looks like this:

```
The types of 'utils.adaptViemWallet' are incompatible between these types
```

It could be that multiple versions of peer dependencies are installed. Review your package lock file for duplicate dependencies.

### No wallet found

If you see an error message that looks like this:

```
Missing a valid wallet
```

or

```
Missing a wallet
```

It could be that you're not providing a valid wallet to the SwapWidget or that you're app is not wrapped in a WagmiProvider. Make sure to provide a wallet to the SwapWidget or double check that your SwapWidget is wrapped by a WagmiProvider. It could also mean that you have two versions of wagmi/viem installed. Make sure that you only have 1 version of wagmi/viem installed as multiple versions can cause issues.
