Details

rspack can't compile in serve mode if the config meets these two conditions:

• it creates a server using the JS APIs, and
• its config file exports 2 or more configs

With configs like this, running rspack serve produces the following error:

RangeError: Maximum call stack size exceeded

Reproduce Steps

See the attached reproduction for a repository that has uses an array of configs and serves with the JS APIs. In that repository, do the following:

1. run pnpm dev:rspack
2. note that the Maximum call stack size exceeded error appears

Note

Starting a server via the cli, with pnpm dev:rspack, works just fine. This multi-compiler scenario only fails if the server is created via the JS APIs.
