BigInt fails to convert to JSON

[wolfadex]

Problem

The SDK sometimes returns a response that includes a value that is a BigInt. When this response is sent to a client from a server, typically using Express, it throws an error because BigInt.prototype.toJSON doesn’t exist.

Workaround

MDN has a guide for working around this issue.

We were facing the same issue while migrating. We're now using https://www.npmjs.com/package/json-bigint to solve it.

You can stringify it like

var stringer = (key, value) => {
     return typeof value === "bigint" ? value.toString() + "n" : value
}

apiCall()
    .then(res => {
        console.log('search', JSON.stringify(res, stringer, 2))
