Impossible to use default value for an Elements Connect field in JSD

How to reproduce :

• Create a Elements Connect live text.
  • Datasource Jira issues (JQL)
  • Query : none
  • Editor : autocomplete (or select list both doesn't work)
  • Template : {summary}
• Go to Administration --> issues -->  custom fields --> configure your custom field.
• Set a default value.
• Add your field in a JSD form.
• Create an issue from JSD form

Current :

the field doesn't work, and the key is displayed.

There is a JS error :

nFeed.js:1 Unhandled exception while calling listener  Object : Error: Syntax error, unrecognized expression: {"keys":["20000"]}

Expected :

The field works and the default value is selected
