AWS "sam deploy" function times out. Stack stays in "REVIEW_IN_PROGRESS" status

Question

I'm trying to deploy a very simple function as shown in below template.yaml file. It creates a "samcli-deploy1629444458" changeset and it stays in "CREATE_IN_PROGRESS" status. When I check details of it there is no changes in it. There is nothing in Events, Resources, Output sections of the stack too. "sam deploy" command fails with attached output and stack stays in "REVIEW_IN_PROGRESS" status and I need to manually delete it.

AWSTemplateFormatVersion: '2010-09-09'
Transform: AWS::Serverless-2016-10-31
Description: >
  AWS Test backend.


Globals:
  Function:
    Timeout: 3
    Runtime: nodejs12.x

Resources:
  HelloWorldApi:
    Type: AWS::Serverless:Api
    Properties:
      Name:API
      StageName: Prod

  HelloWorldFunction:
    Type: AWS::Serverless::Function 
    Properties:
      CodeUri: hello-world/
      Handler: app.lambdaHandler
      Events:
        HelloWorld:
          Type: Api 
          Properties:
            RestApiId: !Ref HelloWorldApi
            Path: /hello
            Method: get

Output of "sam deploy" command.

Waiting for changeset to be created..

Update: If I wait long enough after "sam deploy" command failed and not manually delete the stack, it finally fails with following error:

 1 validation error detected: Value '[AWS::Serverless:Api, AWS::IAM::Role, AWS::Lambda::Function, AWS::Lambda::Permission]' at 'typeNameList' failed to satisfy constraint: Member must satisfy constraint: [Member must have length less than or equal to 204, Member must have length greater than or equal to 10, Member must satisfy regular expression pattern: [A-Za-z0-9]{2,64}::[A-Za-z0-9]{2,64}::[A-Za-z0-9]{2,64}(::MODULE){0,1}]

I couldn't find any long name in the .yaml file which may cause this error.

It's a simple typo, you're missing a colon:

Type: AWS::Serverless:Api

Should be

Type: AWS::Serverless::Api
