"Failed to update project" after cloud-api configuration with 'Create CRUD API for an existing Amazon DynamoDB table'

[ipuris]

I'm using AWS Mobile Hub and AWS Amplify for my React Native project. I successfully have integrated User Sign-in (Amazon Cognito), Cloud Logic (Amazon API Gateway and AWS Lambda), and NoSQL Database (Amazon DynamoDB).

I have tried to create CRUD API using command-line tool according to documentation in https://docs.aws.amazon.com/aws-mobile/latest/developerguide/react-native-access-databases.html

All steps have done successfully, but the last step, awsmobile push gave me an following error.

Failed to update project lumi
{ BadRequestException: Malformed project configuration files. Unable to parse YAML file awsmobile-cli-project/mobile-hub-project.yml Error near line 16: Unterminated inline value

The line 16 in mobile-hub-project.yml is around paths field. After the awsmobile cloud-api configure, the file is changed into:

paths:
          /things: !com.amazonaws.mobilehub.v0.Function 
            name: thingsHandler
            codeFilename: tag:yaml.org,2002:js/undefined ''
            handler: index.handler
            enableCORS: tag:yaml.org,2002:js/undefined ''
            runtime: nodejs6.10
            environment: {}
          '/things/{proxy+}': !com.amazonaws.mobilehub.v0.Function 
            name: thingsHandler
            codeFilename: tag:yaml.org,2002:js/undefined ''
            handler: index.handler
            enableCORS: tag:yaml.org,2002:js/undefined ''
            runtime: nodejs6.10
            environment: {}

where the original file is:

        paths:
          /things: !com.amazonaws.mobilehub.v0.Function 
            description: 'Handler for calls to resource path : /things/{proxy+}'
            environment: {}
            handler: index.handler
            hashcode: Pj6eZDjB+pTLFXuSZjkbZZueZVGd9Kh3nTwjMsU1pAg=
            memorySize: '128'
            modified: '2018-03-26T06:04:44.705+0000'
            name: thingsHandler
            runtime: nodejs6.10
            timeout: '3'
            version: UFr90.5HK9sJdX2dVf9TsWNA1uV5qyAx
          '/things/{proxy+}': !com.amazonaws.mobilehub.v0.Function 
            description: 'Handler for calls to resource path : /things/{proxy+}'
            environment: {}
            handler: index.handler
            hashcode: Pj6eZDjB+pTLFXuSZjkbZZueZVGd9Kh3nTwjMsU1pAg=
            memorySize: '128'
            modified: '2018-03-26T06:04:44.705+0000'
            name: thingsHandler
            runtime: nodejs6.10
            timeout: '3'
            version: wVryIKsxHPdu2SVbnYGaI3ce4f4VL3rA

I found that codeFilename and enableCORS fields are created, and that fields are ended with ''. After I entered awsmobile push in console, the fields are changed again like:

        paths:
          /things: !com.amazonaws.mobilehub.v0.Function 
            name: thingsHandler
            codeFilename: uploads/thingsHandler-20180326182848.zip
            handler: index.handler
            enableCORS: 'tag:yaml.org,2002:js/undefined '''''
            runtime: nodejs6.10
            environment: {}
          '/things/{proxy+}': !com.amazonaws.mobilehub.v0.Function 
            name: thingsHandler
            codeFilename: uploads/thingsHandler-20180326182848.zip
            handler: index.handler
            enableCORS: 'tag:yaml.org,2002:js/undefined '''''
            runtime: nodejs6.10
            environment: {}

Now two single quote in the end of codeFilename field has gone, but there are weird four single quotes in the end of enableCORS. I think there are some parsing error when configuring cloud-api and awsmobile push, but I'm not sure what is the reason of this error. Please give me an advice if you have any idea.

My full configuration for cloud-api is:

$ awsmobile cloud-api configure

This feature will create an API using Amazon API Gateway and AWS Lambda. You can optionally have the lambda function perform CRUD operations against your Amazon DynamoDB table.

? Select from one of the choices below. Create CRUD API for an existing Amazon DynamoDB table
? Select Amazon DynamoDB table to connect to a CRUD API feed
? Restrict API access to signed-in users Yes
Adding lambda function code on:
/Users/ipuris/Developer/lumi/awsmobilejs/backend/cloud-api/feed/
...
Path to be used on API for get and remove an object should be like:
/feed/object/:babyId

Path to be used on API for list objects on get method should be like:
/feed

JSON to be used as data on put request should be like:
{
  "babyId": "INSERT VALUE HERE",
  "category": "INSERT VALUE HERE",
  "creationDate": "INSERT VALUE HERE",
  "details": "INSERT VALUE HERE",
  "endDate": "INSERT VALUE HERE",
  "startDate": "INSERT VALUE HERE",
  "tags": "INSERT VALUE HERE"
}
To test the api from the command line (after awsmobile push) use this commands
awsmobile cloud-api invoke feedCRUD <method> <path> [init]

and the full error message is:

$ awsmobile push

Hi @ipuris did you create the your first cloud api using mobilehub console or the cli?
