Expression editor does not understand complex JMESPath projection

[JaZo]

Describe the bug I use a complex JMESPath projection, which works just fine, but the expression editor has incorrect "syntax highlighting" and gives "[invalid syntax]" as result.

To Reproduce Use this expression:

{{ $jmespath($json, '{reviewers: values[*].{uuid: user.uuid}}') }}

With this input:

{
  "values": [{
      "user": {
        "uuid": "foo"
      }
    },
    {
      "user": {
        "uuid": "bar"
      }
    }
  ]
}

Expected behavior I'd expect correct "syntax highlighting" and result preview.

Environment (please complete the following information):

• OS: Official Docker image (on Kubernetes)
• n8n Version: 1.3.1
• Node.js Version: Whatever the Docker image uses
• Database system: MySQL
• Operation mode: Main

Additional context The projection is perfectly fine when you try it in the tutorial.

Thanks for reporting this.

}} can be escaped in most cases with \ inside strings but this is not an option here.
