Getting "Error: Assertion failed" when trying to sign transaction

[kevinejohn]

I ran into this issue and it seemed to be fixed after reloading node_modules

rm -rf node_modules
npm install

Was there a solution to this? I tried removing node_modules and it didn't work

Hi @n1rna ,
Did you get any solution for this issue, i am also getting same issue. I tried to resolve it by updating bitcore-lib but no luck.

Thanks in advance.

I had to serve the development build to get it to work. I'm guessing it was an issue with whatever the react build scripts were doing to bundle everything in the production build.

I solved this by using react-scripts@^3.4.1 instead of react-scripts@^4.0.0 in my package.json.

You will need to delete package-lock.json and node_modules, then run npm i.

You lose hot module reloading, and some other nice things, but it didn't bother me at all in my case. I always thought HMR was still buggy.

The reason this worked is that Webpack 5 removes a lot of default things, including Buffer, which are needed by BN.js. React scripts 3.x still uses Webpack 4.

To resolve the issue, you can try updating the bn.js package by running the command npm install bn.js in your project directory. After updating, make sure to bundle the file again to incorporate the changes.
