On this directory: https://archive.softwareheritage.org/browse/directory/31b5c8cc985d190b5a7ef4878128ebfdc2358f49/
The readme didn't show up and when i clicked to see the content i got the error below.

After I backed to the directory view- i have the error text in the readme placeholder (I have a local screenshot of this)
