BigNumber undefined

[saugion]

I receive the following error when I build my application:
Uncaught (in promise) TypeError: Cannot read properties of undefined (reading 'from')

It comes from
exports.DEFAULT_VERIFICATION_GAS_LIMIT = ethers_1.ethers.BigNumber.from(70000);
in builder.js

userop version is 0.3.3, ethers is 6.7.1, the latest.

Also constants like ethers.constants.ZeroAddress, ethers.constants.Zero, ethers.utils.hexlify , ethers_1.ethers.providers.JsonRpcProvider are not present in the latest ethers version.

I've also tried different versions but the issue persists. Could it be a conflict with other libraries? Thanks

I think the issue appears because i'm using ethers v6 in my project, but userop has a dependency to ethers v5. The framework i'm using seems to override the v5 with v6 at build time. It would be for userop to use ethers v6.

Got the same issue and you're right its bc ethers deprecated their use of BigNumber. I got around this by just going in and either swapping or wrapping with javascript's BigInt. Not sure if it'll work everytime but worth a try
