How to check if CloudFormation template is correct?

I want to deploy an SQS queue from a CloudFormation template. Is there any issue with my template?

configurationQueue:
    Type: 'AWS::SQS::Queue'
    Properties:
      QueueName: configuration-queue
      VisibilityTimeout: 60
      MessageRetentionPeriod: 86400

SQSQueuePolicy:
      Type: 'AWS::SQS::QueuePolicy'
      Properties:
        PolicyDocument:
          Version: 2012-10-17
          Statement:
            - Effect: Allow
              Principal:
                AWS: '*'
              Action:
                - 'sqs:CreateQueue'
                - 'sqs:DeleteMessage'
                - 'sqs:GetQueueAttributes'
                - 'sqs:GetQueueUrl'
                - 'sqs:ListQueueTags'
                - 'sqs:ListQueues'
                - 'sqs:ReceiveMessage'
                - 'sqs:SendMessage
              Resource: "arn:aws:sqs:us-west-2:****configuration-queue"
        Queues:
          - !Ref configurationQueue

This is the command I used

cfn-lint sqs-resources.yaml

and this is the error

sqs:SendMessage is missing the end quote

CloudFormation Linter in VSCode shows errors inline while authoring templates along with autocompletion and documentation links
