Hf.space/run/predict Data Aggregate howto?

Hi, I understand the syntax curl -X POST -H 'Content-type: application/json' --data '{ "data": ["Jill"] }' https://USER_NAME-SPACE_NAME.hf.space/run/predict
and trying it out on a space with a simple text input e.g.,

curl -X POST -H 'Content-type: application/json' --data '{ "data": ["Jill"] }' https://tomsoderlund-rest-api-with-gradio.hf.space/run/predict

returns a nice

{"data":["Hello Jill!"],"is_generating":false,"duration":0.00015020370483398438,"average_duration":0.00018148869276046753}

But how do I post to a space with sliders, toggles, etc?
For instance, I tried https://huggingface.co/spaces/Svngoku/galactica-base
whose API suggest this Input Payload

  "data": [
    str | None, // represents sample input to preprocess. of 'Input Text' Textbox component
    Any, // represents null of 'Max Length' Slider component
    Any, // represents null of 'Temperature' Slider component
    Any, // represents null of 'Do Sample' Checkbox component

does not work with

POST https://svngoku-galactica-base.hf.space/run/predict
Content-Type: application/json
{ "data": ["Test",128,0.7,True]}

and returns

  "detail": [
      "loc": [
      "msg": "Expecting value: line 2 column 21 (char 32)",
      "type": "value_error.jsondecode",
      "ctx": {
        "msg": "Expecting value",
        "doc": "{ \"data\": [\n  \t  \"Test\",128,0.7,True]}",
        "pos": 32,
        "lineno": 2,
        "colno": 21

I tried many variants, key/value pairs, adding parameters beside data, but none worked.

So, my question is how to aggregate data correctly for spaces with GUI elements when using /run/predict POST? Thanks.

hi @cerkut ,

I tested the request and it works fine

On your browser console

fetch("https://svngoku-galactica-base.hf.space/run/predict", {
  method: "POST",
  headers: { "content-type": "application/json" },
  body: JSON.stringify({ data: ["Test", 128, 0.7, true] }),
.then(res=> res.json())
.then(r=> console.log(r))

and with curl

curl -X POST https://svngoku-galactica-base.hf.space/run/predict -H 'Content-Type: application/json' -d '{"data":["The attention mechanism in LLM is",128,0.7,true]}'
