i'm having this error: 
``var req events.APIGatewayProxyRequest
cannot use req (variable of type events.APIGatewayProxyRequest) as core.SwitchableAPIGatewayRequest value in argument to adapter.ProxyWithContextcompilerIncompatibleAssign

如评论者[mkopriva](https://stackoverflow.com/users/965900/mkopriva)所指出的，你不能直接将`events.APIGatewayProxyRequest`传递给`adapter.ProxyWithContext`。
你需要创建一个新的`SwitchableAPIGatewayRequest`实例，并将其传递给`ProxyWithContext`。
这样应该可以解决你的问题：
```go
import "github.com/awslabs/aws-lambda-go-api-proxy/core"
[...]
func lambdaHandler(ctx context.Context, req events.APIGatewayProxyRequest) (events.APIGatewayProxyResponse, error) {
    return adapter.ProxyWithContext(ctx, *core.NewSwitchableAPIGatewayRequestV1(&req))
}
