Some intercepted errors are lost.

When intercepting an error in a try...catch block, the error should never be lost. I'm currently trying to debug an issue with DefaultDIDAdapter from another project, but the only error I get doesn't have any source, or "caused by".

Here's the actual code from DefaultDIDAdapter:

        try {
            return await this.performRequest(this.rpcEndpoint, request);
        } catch (e) {
            throw new NetworkException("Network error.");
        }

The catch block only forwards the error, but it should instead wrap it like this:

throw new NetworkException("Network error.", e);

This way, the source isn't lost.

This is only an example, but there are many other missing errors.
