The error seems to indicate that PolkadotJS fails to decode the result of a system_health call.

Here's how smoldot reacts to a system_health call:

Here's how upstream Substrate reacts:

Apart from id being returned at the end (and obviously the number of peers being different), it's identical. Therefore I don't think it's a smoldot problem.

According the error, PolkadotJS seems to try decode the response as if it was SCALE-encoded, which it isn't.
