'PosixPermissions' does not exist in type 'IResolvable | OptionsProperty'.

Hi fellow AWS people. I'm trying to set up a datasync task using cdk typescript. The task looks like this:

new datasync.CfnTask(this, 'name', {
      destinationLocationArn: destinationLocation.attrLocationArn,
      sourceLocationArn: sourceLocation.attrLocationArn,
      name: 'task1',
      options: {
        verifyMode: 'ONLY_FILES_TRANSFERRED', // Verify only the data transferred
        overwriteMode: 'ALWAYS', // Overwrite files: Yes
        preserveDeletedFiles: 'PRESERVE', // Keep deleted files: Yes
        bytesPerSecond: 200 * 1024 * 1024, // Bandwidth limit: 200 MiB/s
        taskQueueing: 'ENABLED', // Queueing: Yes
        logLevel: 'TRANSFER',
        objectTags: 'NONE',
        PosixPermissions: 'PRESERVE'
      },
      excludes: [
        {
          filterType: 'SIMPLE_PATTERN',
          value: '*.xlsx', // Exclude: *.xlsx
        },
      ],
      schedule: { scheduleExpression:'cron(30 00/3 ? * MON,TUE,WED,THU,FRI,SAT *)'},
      cloudWatchLogGroupArn: logGroupApprovalZoneSync.logGroupArn,
      tags: [{
          key: 'Key',
          value: 'Value',
      },
      {
          key: 'Key',
          value: 'Value',
      }]
    });

When i try to deploy this code i get this error:

error TS2322: Type '{ verifyMode: string; overwriteMode: string; preserveDeletedFiles: string; bytesPerSecond: number; taskQueueing: string; logLevel: string; objectTags: string; PosixPermissions: string; }' is not assignable to type 'IResolvable | OptionsProperty | undefined'. Object literal may only specify known properties, and 'PosixPermissions' does not exist in type 'IResolvable | OptionsProperty'.

If i delete PosixPermissions from options the task is successfully deployed and works.

According to this documentation:

https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.aws_datasync.CfnTaskProps.html

It should work, but it does not. Can someone help be highlight my mistake?
