Static bundle ethers word list strange error

[trozler]

Hi there,
We are bundling our FE, and encountering a very strange error related to ethers wordlist package.

When we inspect takes us to the following:

Our only ethers dependency is coming from useDapp, which uses "ethers": "5.5.1".

  "dependencies": {
    "ethers": "5.5.1",
     ..... 
  },

We are also using "typescript": "^4.5.5",.

Having spent over a day trying to debug this, any help or pointers would be greatly appreciated.

I have seen others with this problem before as well and it seems to come down to the bundler you are using. Or that some package you are using is referencing one of the pre-bundled dust files in ethers, so it is getting bundled twice?

I haven’t been able to figure out the exact set of tooling and situation causing this problem though.

Even if you get rid of the Wordlist issue, I believe it is actually much deeper; any object that uses inheritance will just be the next problem.

If you can help figure out the problem though, I’m all ears.

Figured it out!

Our issue boiled down to two of our dependencies, having different ethers dependencies:

1. useDapp, direct dependency "ethers": "5.5.1".

2. Typechain V5, which had the following peerDependencies, that were not installed.

    "ethers": "^5.1.3",
    "@ethersproject/bytes": "^5.0.0",
    "@ethersproject/providers": "^5.0.0",
    "@ethersproject/abi": "^5.0.0"

We ended up just removing typechain, as it was not essential.
