Smartsheet API Bug: Copy Sheet with include=forms Fails (Regression)

karthick

Hello Support Team,

We are experiencing an issue with the Smartsheet Copy Sheet API when attempting to include forms.

Endpoint:

POST https://api.smartsheet.com/2.0/sheets/1097094865571716/copy?include=forms

Request Body:

{

    "destinationType": "folder",

    "destinationId": 608151415351172,

    "newName": "new_sheet_included_Forms"

}

Headers:

Authorization: Bearer <validtoken>  Content-Type: application/json

Response:

{

    "errorCode": 4000,

    "message": "An unexpected error has occurred. Please contact the Support team at https://help.smartsheet.com/contact for assistance.",

    "refId": "psrqvp"

}

• This same request worked perfectly until last week.
• Manual copy from the Smartsheet web UI (with forms) still works correctly.
• The issue occurs only when using the API with include=forms.
• We confirmed the request body is valid JSON (other includes work).
• The error seems to indicate an API regression specific to forms.

Please confirm if this is a known issue, and provide guidance or an ETA for a fix.

Thank you,
karthick
