Having issues reusing a stored variable in Graphql query in Karate framework - karate

Question

I have an issue with the variable usage. Tried different options(storing variable differently, declaring, using text for defining the query, storing the query as a variable).
Still have the below error:
"errors": [
{
"message": "invalid input syntax for type uuid: \"#(queueID)\"",
"locations": [
{
"line": 1,
"column": 11
}
],
"path": [
"deleteQueue"
],
"extensions": {
"code": "INTERNAL_SERVER_ERROR",
"exception": {
"name": "SequelizeDatabaseError",
"parent": {
"length": 109,
"name": "error",
"severity": "ERROR",
"code": "22P02",
"position": "34",
"file": "uuid.c",
"line": "137",
"routine": "string_to_uuid",
"sql": "DELETE FROM \"Queue\" WHERE \"id\" = '#(queueID)'"
This are my Gherkin steps:
Given request { query: 'mutation {createQueue(input: {name: "BDD-delete" }) {id} }'}
When method POST
Then status 200
And match response.data.createQueue.name == "BDD-delete"
* def queueID = response.data.createQueue.id
* print queueID
Given request { query: 'mutation {deleteQueue (id:"#(queueID)")} '}
And this is the output, when I print the queueID:
13:14:16.745 [main] INFO com.intuit.karate - [print] 758c0524-b18d-41f6-96aa-9db5eb8a7ac8
Tried using variable for the query
Given text payload =
"""
mutation {
createQueue(input: {name: "BDD-delete" })
{id, name}
}
"""
And the same tried for the deleteQueue
Feels like the issue is related with str and uuid. I must pass a uuid between the brackets in "#(queueID)"

First read this to get a sense of why this is happening: https://github.com/karatelabs/karate#rules-for-embedded-expressions
So try this:
Given request `{ query: 'mutation {deleteQueue (id:"${queueID}")} '}`
The good thing is that Karate supports JS-style placeholder replacement in strings within back-ticks.
