URGENT- Help needed re:mod times dropbox

[ranfl]

What is the problem you are having with rclone?

Trying to create photos and files with custom modification times in dropbox. Also to modify modification times for existing files in dropbox

What is your rclone version (output from rclone version)

1.15.5

Which OS you are using and how many bits (eg Windows 7, 64 bit)

Windows 64bit

Which cloud storage system are you using? (eg Google Drive)

Dropbox

The command you were trying to run (eg rclone copy /tmp remote:tmp)

rclone touch Drop1:SAMURAI.jpg -t 200205

The rclone config contents with secrets removed.

Can't provide, can't copy paste with cmd.
Config uses Dropbox and all defaults no encrypt.

A log from the command with the -vv flag

Photo of it

So I'm trying to modify file timestamps in the dropbox but I keep getting this error message saying I need to upload? Can someone tell me what I'm doing wrong here? Apologies for this I'm giant noob to rclone.

What rclone version you running?
Can you run the same command with -vv and share the output?

I believe this is a limitation of the Dropbox API itself. Relevant docs:

Dropbox

Dropbox supports modified times, but the only way to set a modification time is to re-upload the file.
