Extension fails to run due to Parcel - The Expression evaluated to a falsy value

About four days ago, I ran into an issue where the extension would fail to run with the following error:

🟡 3      | @plasmohq/parcel-runtime Injecting << background-service-runtime >> for static/background/index.js c338908e704c91f1 /home/user/project/browser-extension/.plasmo/static/background/index.ts
🔴 ERROR  | The expression evaluated to a falsy value:

  (0, \_assert().default)(bundleGraph instanceof \_BundleGraph.default)

🟡 3      | @plasmohq/parcel-runtime Injecting << background-service-runtime >> for static/background/index.js c338908e704c91f1 /home/user/project/browser-extension/.plasmo/static/background/index.ts
🔴 ERROR  | The expression evaluated to a falsy value:

  (0, \_assert().default)(bundleGraph instanceof \_BundleGraph.default)

This is weird because I don't think I've changed anything in the project. I maybe ran an

npm install

npm install

recently, and I believe this might be dependency related, but I cannot find where the issue comes from or how to work around it.

Here are the contents of

/home/user/project/browser-extension/.plasmo/static/background/index.ts

/home/user/project/browser-extension/.plasmo/static/background/index.ts

, the file where Parcel breaks:

import "../../../src/background"

import "../../../src/background"

And here's the background file that it's being imported, which is pretty much just an event listener so I'm not sure what the problem is.

import { ScriptMessages } from "~enums/script-messages"

export {}

chrome.action.onClicked.addListener(() => {
  chrome.tabs.query({ active: true, currentWindow: true }, (tabs) => {
    const activeTab = tabs[0]
    chrome.tabs.sendMessage(activeTab.id, { message: ScriptMessages.TOGGLE_EXTENSION })
  })
})

console.log("Background script loaded")

import { ScriptMessages } from "~enums/script-messages"

export {}

chrome.action.onClicked.addListener(() => {
  chrome.tabs.query({ active: true, currentWindow: true }, (tabs) => {
    const activeTab = tabs[0]
    chrome.tabs.sendMessage(activeTab.id, { message: ScriptMessages.TOGGLE_EXTENSION })
  })
})

console.log("Background script loaded")

Any idea how to troubleshoot this issue? I've gone through the issue tracker and I couldn't find anything helpful. I've tried with the

--no-hoist

--no-hoist

flag without any luck, and this happens both when running

dev

dev

and

build
