This is the contents of the 8-node, 6-edge graph input file:

1 2
3 2
3 4
5 6
6 7
6 8

I did the following on "ptest.net.science" and on "net.science" and I got the same results.

I upload this file as a pungraph (undirected graph) on "net.science" and as a pngraph (directed graph) and pungraph on ptest.net.science.

The pngraph is in here: https://ptest.net.science/files/home/cjk8gx/02-may-2023-ptest/
(I deleted the directory and file with the undirected graph version.)

After uploading, I see the file if I hit reload. See Attachment 1.
When click on the graph, I see the tabs: overview, metadata, and provenance. See Attachment 2.
I figured I'd see a tab for Data and that i'd be able to view this file.
Why is the Data option not shown?

Now I want to plot the graph. I select the graph visualization tool, which is: net.science/generate_graph_visualization. see Attachment 5.
I fill out the form (see attachments 3 and 4), and when I click submit, I get this error:
"An internal error occurred. Please try again."
So the plotting code is not working for me.

It's as if the original data file is bad, but I don't know why. Which is why I want to see the file contents within net.science.

Also, by now, one would think metadata would be done on such a tiny graph, but no metadata exist. Again, indicating a bad graph file.

This is failing at the very beginning. Your upload never succeeded and we'll need to investigate why that was the case. Notice your file is "empty" and has no version. That is why the rest of the sequence was failing.

Here is the error message on a new upload process. I don't know how I did not see this error message 500 before. It is in red, after all.

It appears that it is having trouble accessing the underlying storage from Rivanna. I'm looking into this issue.

This problem was that the underlying storage was responding very slowly. Creating a directory was taking 30 minutes and so the actual underlying upload was failing here. I reported this to Research Computing. Recently it started performing reasonably well again, so I retested uploads in the UI and it is working again now.
