Hey all! Howdy? When I run an AWS CLI command to retrieve values from DynamoDB, as shown below, everything works fine. The query returns 73MB of data as expected:

aws dynamodb query --table-name a-table \
    --key-condition-expression "#p = :projectval" \
    --expression-attribute-names '{"#p":"project"}' \
    --expression-attribute-values '{":projectval":{"S":"A_PROJECT_NAME"}}'

(s/defn ->query :- wire.out.dynamodb/Query
  [table-name :- s/Str
   item :- (s/pred map?)]
  {:op      :Query
   :request {:TableName              table-name
             :KeyConditionExpression "#p = :projectval",
             :ExpressionAttributeNames {"#p" (str (-> item keys first name))}
             :ExpressionAttributeValues {":projectval" {:S (-> item vals first str)}}}})
