Pre-annotations of TextArea

[michaelachmann]

I ran into trouble when adding pre annotations using the SDK for textareas. Here's my initial bug report: https://github.com/heartexlabs/label-studio/issues/3941

I think there might still be a bug in the SDK causing the uploaded tasks pre-annotations to contain the following

"value": {
  "textarea": [
    "... transcription ..."
  ]
},

instead of

"value": {
  "text": [
    "... transcription ..."
  ]
},

Could you please share your SDK code where you create pre-annotations?

Sure, it's basically these two steps:

1. Create a new project and Interface:

   
   interface = """
   <View>
   <Audio name="audio" value="$audio" zoom="true" hotkey="ctrl+enter" />
   <Header value="Provide Transcription" />
   <TextArea name="transcript" toName="audio"
           rows="5" editable="true" maxSubmissions="1" />
   </View>
   """

project_name = "Audio Project" ls = Client(url=labelstudio_url, api_key=labelstudio_key) project = ls.start_project( title=project_name, label_config=interface, )

2. Upload Tasks with pre-annotations
```python
project.import_tasks(
        df_tasks.to_dict('records'),
        preannotated_from_fields=['transcript'])

it won't work this way, because preannotatored from fields work for choices only. Check this video https://labelstud.io/guide/predictions.html#Prepare-pre-annotations-for-Label-Studio and prepare your annotation json following this video tutorial.
