How to create a EventBridge scheduler with Node.js

Question

My setup is pretty simple. I am using sst to create a graphql lambda endpoint. Sst also creates an EventBridge Bus and an EventBridge Rules. So whenever I send the proper event to the bus this trigger a second lambda function that sends an email containing the report requested by the user. Everything works as expected till this point.

    import { EventBus } from "@serverless-stack/node/event-bus";
    import aws from "aws-sdk";

      await new aws.EventBridge()
        .putEvents({
          Entries: [
            {
              EventBusName: EventBus["AffinityBus"]?.eventBusName,
              DetailType: "reportInput",
              Detail: JSON.stringify({
                endDate: params.endDate,
                startDate: params.startDate,
                filters: params?.filters,
                campaignId: params?.campaignId,
              }),
              Source: "sendCampaignReportByEmail",
            },
          ],
        })
        .promise();

But my requirements demand that the user should be able to schedule this report email. This is the main reason I am using EventBridge in the first place. He its why I am trying to do

    import {
      CreateScheduleCommand,
      FlexibleTimeWindowMode,
      SchedulerClient,
    } from "@aws-sdk/client-scheduler";

    const ebc = new SchedulerClient({ region: awsConstants.AWS_REGION });
    const command = new CreateScheduleCommand({
        Name: "newScheduler",
        GroupName: "affinity",
        ScheduleExpression: `repeat(${calculateRepetition(params)} minute)`,
        FlexibleTimeWindow: { Mode: FlexibleTimeWindowMode.OFF },
        Target: {
          Arn: "arn:aws:scheduler:::aws-sdk:eventbridge:putEvents",
          RoleArn: "arn:aws:iam::xxxxx:role/name",
          Input: JSON.stringify({
            endDate: params.endDate,
            startDate: params.startDate,
            filters: params?.filters,
            campaignId: params?.campaignId,
          }),
        },
        StartDate: new Date(params.startDate),
        EndDate: new Date(params.endDate),
      });
    
    await ebc.send(command)

This is the error I am facing, but that is very weird, because there is no Entries field on the awsv3 typescript types. What should I do??

  }
}

I can replicate the same error with the cli. By running the following command

aws scheduler create-schedule --name cevent-bridge-schedule --schedule-expression 'rate(5 minutes)' --target '{"Arn": "arn:aws:scheduler:::aws-sdk:eventbridge:putEvents", "RoleArn": "arn:aws:iam::xxxx:role/myrole", "Input": "{\"Entries\": [{\"EventBusName\":\"dev-affinity-appsync-AffinityBus\", \"DetailType\":\"reportInput\" , \"Detail\":\"{}\" , \"Source\": \"sendCampaignReportByEmail\" }]}" }' --flexible-time-window '{ "Mode": "OFF"}' --region us-east-1  --debug
