The new file button provides the file as base64 data, which does not work when trying to upload to a rest endpoint via Form Data and selecting "file" for the body value type.
Your documentation still references the old file picker component that provides the correct file data object.
Hey jmc, you can create a new JS transformer in the query editor at the bottom of the page. In the same dropdown you would use to create any query type.
Hey @andr3w unfortunately there are no updates at this time. I've updated the internal ticket to advocate for a permanent fix, but this ticket is still currently in the backlog. We can update this thread here when we have any additional information on its status.
