Describe the problem and steps to reproduce it:

  • Build extension (or use the already built zip)
  • Upload it
  • Get an unknown error while validating

What happened?

  • I want to update my Extension but am unable to due to FF AMO telling me that it was unable to verify "due to an unexpected error."

What did you expect to happen?

  • It uploads and verifies correctly

Anything else we should know?

Chrome web store took it just fine (it is a WebExtension-Api based extension with polyfills for Chrome as it doesn't use the browser interface).

This is the result I get:


I am able to load it via about:debugging just fine, though about:addons doesn't take it due to it not being signed (I assume AMO does that automatically?).

I assume it's because the linter chokes on the very large minified files your add-on contains. It does work locally on my machine, but it takes a significant amount of time and memory to process (more than 30 seconds and 1GB memory). It's probably hitting against memory or time execution limits in production...

Good to know. I've implemented splitting chunks by using html-webpack-loader@next (4.0 beta) and moved my background script to the background html page. This reduced the uncompressed size by ~5mb and it went through flawlessly.
