Network: besu running ibft on kaleido

This results in error and Memento is unable to scrape data:

❯ curl -X POST --data '[{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0x1d330",true],"id":"55104dc76695721d"}]' https://[redacted]:[redacted]@[redacted].de0-aws.kaleido.io

But this one works just fine:

❯ curl -X POST --data '{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":["0x1d330",true],"id":"55104dc76695721d"}' https://[redacted]:[redacted]@[redacted].de0-aws.kaleido.io

When running with batch calls, the node responds with:

"{\"jsonrpc\":\"2.0\",\"id\":null,\"error\":{\"code\":-32700,\"message\":\"Parse error\"}}"
