Can't set Connect field values when importing issues from CSV

How to reproduce

• Configure a connect field (i.e.: an issue picker using "Jira Issues (JQL)" datasource
• Prepare a CSV file for import

  Summary,Connect field
  Hello world,10000
  Salut le monde,10001
  

• Import the CSV file (External system import feature of Jira)

Current

Connect field is not set:

Cannot add value [ [VAUE] ] to CustomField CSR Number in Issue with summary '...'. Probably value was in incorrect format

Expected

It works

Workaround

Enclose the connect field value in a JSON document.

{
    "inputValues":["10000"]
}

Where 10000 is the value of the Connect field
