Expected Behavior

dynamodb Client.Query to return without error

Current Behavior

dynamodb Client.Query returns error:

operation error DynamoDB: Query, https response error StatusCode: 200, RequestID: GUR48MP1C12O956O84J2H67F7NVV4KQNSO5AEMVJF66Q9ASUAAJG, deserialization failed, failed to decode response body, read tcp 169.254.76.1:56796-\u003e52.94.0.72:443: use of closed network connection"}

Reproduction Steps

result, err := db.Query(
        ctx,
        &dynamodb.QueryInput{
                TableName:                 aws.String(name),
                ConsistentRead:            aws.Bool(true),
                Limit:                     aws.Int32(count),
                KeyConditionExpression:    aws.String(keyConditionExpression),
                ExpressionAttributeValues: expressionAttributeValues,
                ExclusiveStartKey:         exclusiveStartKey,
        },
)

For what it's worth, I actually get two different stack traces when I run with the tracing code. The one I provided in the description matches the time I saw the closed network connection error, and happens very infrequently. Hover, I frequently get the trace:

but it doesn't seem to correspond to an error in my client code.

TYVM for taking the time to repro. I'll try to deep dive this week or early next.

These traces certainly appear to demonstrate that it's net/http that's ultimately closing the conns out from under us. Whether we indirectly caused said close remains to be seen.
