[liuy129]

Describe the bug Attempted to upgrade LabelStudio from 1.7.2dev to 1.9+~1.13.1 However, encounter an Runtime error message box whenever trying to draft a new annotation. Here is the stacktrace as illustrated:

TypeError: Got a `TypeError` when calling `AnnotationDraft.objects.create()`. This may be because you have a writable field on the serializer class that is not a valid argument to `AnnotationDraft.objects.create()`. You may need to make the field read-only, or override the AnnotationDraftSerializer.create() method to handle this correctly.
Original exception was:

To Reproduce

Labelling config:

<View>
  <Header value="Select label and start to click on image"/>
  <Image name="image" value="$image" width="1500px" rotateControl="true" contrastControl="true" brightnessControl="true" show_skip_button="true" zoom="true" negativeZoom="true"/>

  <Labels name="labels" toName="image" opacity="0.1">
    <Label value="ObjectToFind" background="#ff6b6b" selected="true"/>
   </Labels>
    <MagicWand name="magicwand" toName="image" opacity="0.7" blurradius="15" defaultthreshold="12"/>
    <Brush name="brushes" toName="image"/>
    <Polygon name="polys" toName="image" opacity="0.1"/>
    <Rectangle name="rects" toName="image"/>

  <TextArea name="comment" value="comment here" toName="image" editable="true" showSubmitButton="true" skipDuplicates="true" maxSubmissions="3" perRegion="false" placeholder="Recognized Text"/>

  <Text name="ratingTxt1" value="Rate the above annotation on a scale of 0 to 5 stars:"/>
  <Text name="lineBreak1" value="----------------------------------------------------------"/>
  <Rating name="rating" toName="image" maxRating="5" defaultValue="0" required="true" requiredMessage="please rate and update" icon="star" size="large"/>
  <Text name="lineBreak2" value="----------------------------------------------------------"/>
panel;"/>
</View>

Steps to reproduce the behavior:

1. upgrade LS from 1.7.2dev to 1.13.x
2. use "Python manage.py xxx" (where xxx is migrate, collectstaic, or runserver)
3. wait for the local sqlite3 database to finish migrate
4. Go to any 'project'
5. Click on any 'task'
6. start annotating the image
7. within five seconds, runtime error occurs and keep popping up

Expected behavior Expect no Runtime error when drafting annotations

Screenshots Runtime error:

Labelling config error:

Environment (please complete the following information):

• OS: Windows 10
• Label Studio Version 1.13.1
• Python Version: 3.10
• Browser: Edge and Chrome

Additional context in addition, the Labelling config also shows the same error as shown in the second screenshot

Try to go to Project settings => Danger Zone And click Reset Cache button there.

that resolved my issue. Is that typical when upgrading Label Studio? I have quite a number of projects. I wonder if I can resolve this all at once?
