Tests (i.e. nodejs/test) fail with the addition to chain parameters due to type mismatch in expectedJsons.ts.

It would be nice if you could update the tests for nodejs/test/client.test.ts as well to ensure compatibility with both v1 and v2 api.

They don't fail for me 🤔
(Maybe it has been fixed elsewhere in the mean time)

Okay I didn't rebuild common, that is why it didn't failed. 🙃

But I've fixed it now.

I didn't update the v1 tests, but fixed the types (the keys are not in the chainParameters for v1)
