Issue Summary:

When using automation to clone a ticket with an attached form, the values in the form are also copied. However, if the User Picker field in the trigger ticket's form contains only one user, the automation fails with the following error:
"Unable to update value for form field ユーザーピッカーを追加しますか？: Choice option doesnt exist."

If the User Picker field contains two or more users, the automation completes successfully without error.

Steps to Reproduce:

1. Create a ticket with a form attached.

1. In the form, set the User Picker field (e.g., "ユーザーピッカーを追加しますか？") to contain only one user.

1. Set up automation to clone the ticket and copy form values.

1. Trigger the automation.

 Expected Results:

The automation should successfully clone the ticket and copy the form values, regardless of the number of users in the User Picker field.

 Actual Results:

If the User Picker field contains only one user, the automation fails with the error:
"Unable to update value for form field ユーザーピッカーを追加しますか？: Choice option doesnt exist."
If the field contains two or more users, the automation works as expected.

 
Error recorded:

Unable to update value for form field 記入者⑤を追加しますか？:
Choice option doesnt exist.

 Workaround:

Add two or more users to the User Picker field before triggering the automation to avoid the error.
