A new hublData.hubl.html file is now showing up in my custom modules folders.

Out of nowhere, a new file, hublData.hubl.html, surfaced in my custom module folders about a month ago. Initially, it only existed as hublData.hubl, but as of yesterday, the same file now bears a .html extension.

Despite my efforts in scouring through developer documentation, I haven’t unearthed any relevant information about this file. Two key questions remain:

  1. What is the purpose of this file?
  2. How can I either delete the file or eliminate the .html extension?

It’s worth noting that the sheer volume of custom modules makes manual removal of the extension impractical.
