[Bug]: GraphQL query variable interpolation "String cannot represent a non string value"

[vasileermicioi]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

Variable interpolation in the GraphQL queries is raising errors "String cannot represent a non string value".
But it works if I copy the same content (including the variable interpolation) in a temporary state, and put it in the graphql query.

This doesn't work

This works

Expected Behavior

GraphQL query to work with variable interpolations

Steps to reproduce

1. Create a module
2. Create a input continentCode
3. Create a GraphQL query

url: https://countries.trevorblades.com/

body:
{
countries(filter: {continent: {eq: "{{continentCode.value}}"}}) {
code
name
capital
}
}
4) result
error "String cannot represent a non string value"
