After some testing, @cryptotavares and I identified that the issue is on the API side, specifically with the Priority Connect RPC used for this chain. The RPC is provided by Infura, and we've already shared the error details with their team. I'll update the ticket once we hear back from them.

Infure created an incident https://consensys.slack.com/archives/C08E29KDCBH and after a fix, the RPCs started to work and validate the requests.
