I am getting a awrning when trying to upload files to Hubshare "object required" and then in the upload box a message saying error during upload. Can anyone give me some pointers whey this might be happening.

One potential reason is that the class has mandatory properties which are not provided. This support article has more information: Hubshare's M-Files widget and "Internal server error, please retry"

If the vault is on a self-hosted server, you may want to check the server logs like described in the article. Those may contain further hints on what went wrong.

If you can't figure it out, you can reach out to the support teams via the Support Portal.

Hi Jonas, Thank you for your reply. It isn't self hosted, but is a single instance Hubshare site. I have looked at mandatory fields, and allowed for that. I have also created a new class with no mandatory fields, but I get the same message. If I use a creator widget, I can upload documents, but in the creator widget, you can select an object type for the upload, which you can't in the explorer and views widget. Thank you for the article  link. I'll take a look and see if there is anything in it that might help.
