Form Editor crashes when FEEL expression is created in the File Picker form element

[GeethaParthasarathy]

Describe the bug

When we create a FEEL expression in the supported file formats field of the File Picker form element, the current form editor crashes such that it affects the subsequently created forms as well

Steps to reproduce

1. Create a form with File picker form element
2. Add a Feel expression to the supported file formats field and create a unparsable feel expression
3. Correct the unparsable feel expression
4. Even after correcting we could see the following:
   -> Feel pop up editor does not open up
   -> Form editor properties panel is frozen
   ->subsequently opened up forms are all affected

Expected behavior

Adding an unparsable FEEL expression to the form field should not break the form editor

Environment

• OS: [e.g.MacOS 10.2]
• Camunda Modeler Version: [5.29.0 rc-0]
• Execution Platform: [ Camunda 8]
• Installed plug-ins: [...]

@GeethaParthasarathy I can't reproduce it. Did I do something wrong? Could check if the steps are correct?

Hey @vsgoulart I guess there is a missed step this issue happens when there is an error in your Feel expression and then even if you rectify it the form editor is broken
