My code to delete the objects look like this:

const s3 = new AWS.S3({
    endpoint: spaceEndpoint,
    accessKeyId,
    secretAccessKey,
})

const params = {
    Bucket: bucketName,
    Delete: {
        Objects: assetsToDelete,
    },
}
try {
    const res1 = await s3.deleteObjects(params).promise()
}catch(e){
    console.log(e)
}

value of assetsToDelete is

  {
    Key: 'userId/folderName/object1'
  },
  {
    Key: 'userId/folderName/object2'
  }
]

But I'm getting an error:

InvalidArgument: Invalid argument.
   ErrorSTACK {
  code: 'InvalidArgument',
  region: null,
  time: 2021-02-12T20:30:42.055Z,
  requestId: null,
  extendedRequestId: undefined,
  cfId: undefined,
  statusCode: 400,
  retryable: false,
  retryDelay: 81.1455003388468
}

The above configuration works fine for upload and listing objects. I'm trying to delete from a gcp bucket.
