Error when updating: k is not defined

[wishinghand]

I'm running in Docker, FVTT version 9, build 269.

I saw that there was an update, so I tried to pull it in using Foundry's system updater. A red error popup with only the phrase k is not defined was shown. I refreshed and tried again with the console open. No errors in the log, but this was in the response to the API request of updating the system:

"ReferenceError: k is not defined\n at Function.getManifest (file:///home/foundry/resources/app/dist/packages/package.mjs:1:7288)\n at runMicrotasks ()\n at processTicksAndRejections (node:internal/process/task_queues:96:5)\n at async Module.checkPackage (file:///home/foundry/resources/app/dist/packages/views.mjs:1:1295)\n at async SetupView.handlePost (file:///home/foundry/resources/app/dist/server/views/setup.mjs:1:1631)"
