EC2 StartInstance "SyntaxError: Unexpected token i in JSON at position 0"

[JohnnyPicnic]

When I put an instance Id in the EC2 node I get: "SyntaxError: Unexpected token i in JSON at position 0"

When passing msg.InstanceIds.1=isntanceid I get: "failed: InvalidParameterType: Expected params.InstanceIds to be an Array"

Also it’s asking for an array, but it doesn’t look like you’re passing one. Try msg.InstanceIds=[isntanceid]

I'm using an inject node to pass the parameters. EC2 StartInstance. tried setting msg.InstanceIds=[isntanceid] and got "SyntaxError: Unexpected token i in JSON at position 1"

Sorry I'm away at the moment, and dont have a node-red instance available. Can you wire the inject into a debug node (configured to show the whole message) and paste the output.

[JohnnyPicnic]

msg : Object object _msgid: "a97e3cd9f65ee48a" payload: "" topic: "" InstanceIds: "[i-030fa455efd7291aa]"

[JohnnyPicnic]

Ah I got it. Modified this from the Node-Red forum. In a function node: `var myArray = context.get("myArray");

if(!myArray) { console.log("Set the array on context memory"); context.set("myArray", []); myArray = context.get("myArray"); }

myArray.push(msg.payload); msg.InstanceIds = myArray; return msg;`

And injected my instance id as the msg.payload
