FileLinkValue update via change_multiple_column_values

Hi everyone!

I’ve been experimenting with the change_multiple_column_values mutation to update the Files Column with external links (like Google Drive). While the documentation currently lists this as unsupported for this specific mutation, I found that it actually works—with one major catch regarding fileId.

The Method

I am using the following mutation:

mutation updateFileLink ($columnValues: JSON!) {
  change_multiple_column_values(
    item_id: "my_item_id",
    board_id: "my_board_id",
    column_values: $columnValues
  ) {
    id
  }
}

With this JSON as columnValues variable:

{
  "file_column_id": {
    "files": [
      {
        "fileId": "file1_id",
        "fileType": "GOOGLE_DRIVE",
        "linkToFile": "https://drive.google.com/...",
        "name": "file1.pdf"
      }
    ]
  }
}

The Issue: The fileId Dependency

The mutation is successful and the link appears perfectly in the WebUI. However, I’ve run into a significant backend issue:

1. Omitting fileId: If I don't provide a fileId in the mutation, the link still shows up in the UI. But, any subsequent API query to fetch that column's value crashes (it returns a null for fileId which seems to break the internal GraphQL resolver).

2. Reusing fileId: If I manually provide a value for fileId (taken from already existing file) the query works. I’ve tested reusing the same fileId across multiple items and it "works," but this feels like just asking for trouble.

My Questions

Since the official add_file_to_column mutation is geared toward file uploads (assets) rather than external links, I’m wondering about three things:

• Roadmap: Are there plans to officially support FileLinkValue in the change_multiple_column_values mutation?

• Safety: Is it "safe" (even if unsupported) to reuse a fileId from file already existing on the service, or will this cause orphaned metadata/collisions in the long run?

• Alternatives: Has anyone found a way to let the monday.com backend generate the fileId for external links via API without it crashing the query?
