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?

Answer

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 :)
