LastEvaluatedKey in QueryOutputTableTypeDef not treated as Optional contrary to boto3 documentation

[Ricool06]

Describe the bug
LastEvaluatedKey in QueryOutputTableTypeDef is not treated as Optional by boto3-stubs despite it only being present if a DynamoDB query requires pagination. The documentation for boto3 implies that it is optional here.

Happy to submit a PR, but not 100% sure how the type builder works yet.

To Reproduce
Steps to reproduce the behavior:

1. Install boto3-stubs[...]
2. Run mypy on the following code sample

import boto3
from mypy_boto3_dynamodb.type_defs import QueryOutputTableTypeDef

response: QueryOutputTableTypeDef = {
        "Items": [],
        "ConsumedCapacity": {},
        "ResponseMetadata": {
            "RequestId": "",
            "HTTPStatusCode": 200,
            "HTTPHeaders": {},
            "RetryAttempts": 0,
        },
        "Count": 0,
        "ScannedCount": 0,
        # "LastEvaluatedKey": {},
    }

Actual output

 error: Missing key "LastEvaluatedKey" for TypedDict "QueryOutputTableTypeDef"  [typeddict-item]

Expected output

Success: no issues found in 1 source file

Additional context
Ubuntu 20.04, installed with poetry add boto3-stubs, boto3 version 1.34.146.

Hello. Thank you for the report.

Unfortunately, there is no way to tell which keys in output shapes are required or optional, because required array is not present in botocore shapes in 99% of cases. So, builder considers all output keys as required by default.

However, there is a way to manually mark any key as optional here: https://github.com/youtype/mypy_boto3_builder/blob/main/mypy_boto3_builder/type_maps/required_attribute_map.py

So, I am going to add ServiceNameCatalog.dynamodb -> ALL -> LastEvaluatedKey = False in the next release. Let me know if you want to submit a PR.

Fixed in the latest release: https://github.com/youtype/mypy_boto3_builder/releases/tag/8.2.0

Please update mypy-boto3-dynamodb and let me know if it works as expected.

Well, if you find any other keys that should be marked as NotRequired in output shapes - you can submit a PR.

Will do, thanks for the hard work. 🙏
