I am running rdiffweb inside a Docker container on Unraid. (github for the container is here: https://github.com/waazaa-fr/rdiff-backup-rdiffweb)

When I try to click down into the repository to an individual file, I get a 500 error, and when I attempt to remove a repository, I see this:

Oops! 400 Bad Request

Sorry, an error has occured.

Confirmation: This field is required.

I'm not sure if this is a permissions issue, or if there is something obvious I am not doing right. Any help on finding the source of these issues would be appreciated. Here is a log snippet:

This is obviously unexpected.

When you try to delete a repository. You should be prompted to confirm the repository name with a dialog similar to the following.

Could you confirm if this is working on your side ?

Oooh... quick response. I think I will try your Docker image and see how I do with that. I just found the one I am using from the Unraid application catalog.

This is what my confirmation dialog looks like. I'm guessing this means I am not running the correct version of something, or some kind of dependency is missing somewhere. As I said above, I will try again with your official Docker and see what I get. Thanks for the quick response!

OK, I have set up the official docker.

The restore problem is gone, I can click down into files and folders just fine. I ran a test to see what a deleted file or folder would do, just so I know how it works, and I see they show up with the grey background. I think that's awesome, not having to dig through versions to find the file I want.

However, I tried to delete the repository and still got the same results as above. I usually do my personal browsing in Firefox, but I tried Chrome as well, and the confirmation dialog still looks like the one above. Obviously, deleting a repository is not something one does every day, so that's not a huge concern.

This is very strange. When you open the rdiffweb interface in firefox or chrome. Could you check if there are any javascript errors using the Web Developer Tools Console ?

PS. You might also be interested in Minarca (https://minarca.org) which is based on rdiffweb but provides agents for Windows, Linux and MacOS. But the Docker Image for Minarca is still in beta.

I created a second small repo for testing. I don't see any javascript errors in the console when I push the "delete" button. I don't know if it helps, but here is the code for the delete modal, copied from Chrome's Dev tools:

<div class="modal show" id="delete-repo-modal" tabindex="-1" role="dialog" aria-labelledby="delete-repo-modal-title" aria-modal="true" style="padding-right: 15px; display: block;">
<div class="modal-dialog">
<div class="modal-content">
<form action="http://192.168.35.8:8080/delete/duane/" method="post" role="form" autocomplete="off">
<div class="modal-header">
<h4 class="modal-title" id="delete-repo-modal-title">Confirmation required</h4>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<input type="hidden" name="action" value="">
<p>You are about to permanently delete this repository. Deleted repository CANNOT be restored! Are you ABSOLUTELY sure?</p>

</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="submit" class="btn btn-danger">Delete</button>
</div>
</form>
</div>

</div>

</div>

Just to see if it was something unintended that might have been in a recent update, I rolled my container back to 2.9.7, and observed the same behavior there.

This issue is not a big deal for me, I really only intend to have one repository in the system anyway, so I should not need to delete one, I just found the issue because I was playing around with rdiff-backup and rdiffweb to see how they worked and get my configuration settled down. If you have other questions, or want me to look at anything else, I am willing, but I'm also OK with the issue just being dropped, your choice.
