Dropbox upload node fails to overwrite existing files

[Polonco]

Bug Description

The "Dropbox Upload File" node does not overwrite files when a file with the same name already exists in Dropbox, despite the documentation in the file path help popup stating: "Existing files get overwritten."

• The issue does not occur during manual testing; it only appears when the workflow runs in production.
• Appending a unique identifier (e.g., date) to the filename bypasses the issue.

To Reproduce

1. Add a "Schedule Trigger" node to start the workflow.
2. Use a "Read File" node to read a file from the local disk.
3. Add a "Dropbox Upload File" node and set the upload path to use the same filename for every execution.
4. Run the workflow.

Expected behavior

The file should be uploaded and overwrite the existing file in Dropbox, as described in the documentation.

Observed Behavior: The workflow fails to upload the file if a file with the same name already exists in Dropbox.
