Hi @digiform,
I took a look at the diagnostic, but it appears that the bulk download is still in progress there, so I don’t see any errors stopping it.
If this is a very large folder, you can try to force the download, regardless of the number of errors that may be encountered along the way, by using a script.
Take a look here for instructions on doing this and let me know if you need any additional info on trying it: How can I force a recursive download with the CLI?
