Converting WOQL-JS to WOQL-JSON to WOQL-JS did not work: `SYNTAX ERROR: WOQL.decimal is not a function`

[alexander-mart]

After toogle mode to JSON and back to WOQL and again to JSON (two times) with example query from docs i receive error: WOQL.decimal is not a function

Doc page:
https://terminusdb.com/docs/maths-based-queries-in-woql/

How to reproduce:

1. Paste example in WOQL-mode and run:
   SERVER ERROR: Not well formed WOQL JSON-LD

let v = Vars("result");
evaluate(times(2,3), v.result)

2. Convert to JSON:

{
  "@type": "Eval",
  "expression": {
    "@type": "Times",
    "left": {
      "@type": "ArithmeticValue",
      "data": {
        "@type": "xsd:decimal",
        "@value": 2
      }
    },
    "right": {
      "@type": "ArithmeticValue",
      "data": {
        "@type": "xsd:decimal",
        "@value": 3
      }
    }
  },
  "result": {
    "@type": "ArithmeticValue",
    "variable": "result"
  }
}

3. Convert to WOQL:

WOQL.eval(WOQL.times({"@type":"xsd:decimal","@value":2}, {"@type":"xsd:decimal","@value":3}), "v:result")

4. Convert to JSON:

{
  "@type": "Eval",
  "expression": {
    "@type": "Times",
    "left": {
      "@type": "xsd:decimal",
      "@value": 2
    },
    "right": {
      "@type": "xsd:decimal",
      "@value": 3
    }
  },
  "result": {
    "@type": "ArithmeticValue",
    "variable": "result"
  }
}

4. Convert to WOQL:

WOQL.eval(WOQL.times(WOQL.decimal(2), WOQL.decimal(3)), "v:result")

5. Convert to JSON:
   ❌ SYNTAX ERROR: WOQL.decimal is not a function

From Discord:

LaurentS:
We tried replacing xsd:decimal with its equivalent (according to the docs) xsd:double but it didn't help.

@GavinMendelGleason Give me a hint where to look at the code that is responsible for this? I'll try to find a bug or missing method

It's working in v11.1.14
