Cannot use 'expr.Names()' (type map[string]*string) as the type map[string]string

[BElluu]

Hello,
I tried use expressions but I have error. I tried use example from documentation.

	// keyCond represents the Key Condition Expression
	keyCond := expression.Key("someKey").Equal(expression.Value("someValue"))
	// proj represents the Projection Expression
	proj := expression.NamesList(expression.Name("aName"), expression.Name("anotherName"), expression.Name("oneOtherName"))

	// Add keyCond and proj to builder as a Key Condition and Projection
	// respectively
	builder := expression.NewBuilder().WithKeyCondition(keyCond).WithProjection(proj)
	expr := builder.Build()

	queryInput := dynamodb.QueryInput{
		KeyConditionExpression:    expr.KeyCondition(),
		ProjectionExpression:      expr.Projection(),
		ExpressionAttributeNames:  expr.Names(),
		ExpressionAttributeValues: expr.Values(),
		TableName: aws.String("SomeTable"),
	}

On expr.Names() and expr.Values() I have error:
Cannot use 'expr.Names()' (type map[string]*string) as the type map[string]string

Is it bug in documentation or I doing something wrong?

@BElluu from your description of the issue it sounds like you're trying to use the v1 SDK's expression package with the v2 SDK's dynamodb#QueryInput type. The types and utilities in the v1 SDK are not compatible with the v2 SDK.

I think you want to use the v2 SDK's expression package instead, github.com/aws/aws-sdk-go-v2/feature/dynamodb/expression. If you're using helper tools like goimports or similar IDE tools, its possible these are adding the wrong version SDK as import.
