AppSync resolver to Aurora Serverless - '$id' inserting as string

Question

Hi,  
  
I'm trying to follow the tutorial at: https://docs.aws.amazon.com/appsync/latest/devguide/tutorial-rds-resolvers.html  
  
I followed the docs closely, but in my input resolver, the '$id' argument is being inserted as '$id' into the table and not a proper ID value like '8b9afc0a-6d07-4b7b-b504-aff44ccac392'.  
  
{  
    "version": "2018-05-29",  
    "statements": \[  
        "insert into Test VALUES ('$id', '$ctx.args.input.testValue')",  
        "select * from Test WHERE id = '$id'"  
    ]  
}  
  
As a test, I tried '$util.autoId()' which did give me a proper ID value, but then the select * statement broke.   
  
Any ideas?

Are you doing the util.autoId outside the statement block in the following manner? This will generate the id variable that will be set inside the statements.

```
#set($id=$utils.autoId())
{
    "version": "2018-05-29",
    "statements": [
        "insert into Pets VALUES ('$id', '$ctx.args.input.type', $ctx.args.input.price)",
        "select * from Pets WHERE id = '$id'"
    ]
}
```

Thank you!  
  
Yup, it's right there in the sample, the darker font in italics made it blend in. Working now :)
