The KeyConditionExpression is invalid due to the use of multiple attribute names within a single condition

I am trying to query a DynamoDB table using GraphQL


    TableName: "JobInfo",
    IndexName: "tableauGSI",
    KeyConditionExpression: "tableauGSI_Tableau = tableau AND #D BETWEEN :startDate AND :endDate",
    ExpressionAttributeNames: { "#D": "date" },
    ExpressionAttributeValues: {
      ":startDate": startDate,
      ":endDate": days
    },
    ReturnConsumedCapacity: "TOTAL"

However, upon executing the query, I encountered this error: "Invalid condition in KeyConditionExpression: Multiple attribute names used in one condition"

Answer №1

When using "tableauGSI_Tableau" as your partition key, you should avoid comparing it to a field called "tableau" as this may not be allowed. If "tableau" is just a value, consider escaping it or including it in ExpressionAttributeValues.
