[oleksandrSydorenkoJ]

Preconditions:
Active schain medium type
Oracle-demo

Versions:
skalenetwork/schain:3.16.1-beta.0

Steps to reproduce:

1. Run oracle demo for eth_gasPrice

            '"cid":<skaleChainId>,"uri":"eth://","jsps":["/result"],encoding":"json","ethApi":"eth_gasPrice","params":[]'

2. check output

Expected state:
Oracle request should return readable error - not supported method for Oracle.
For the invalid request Oracle should return the full request line with detailed mistake in request.

Actual state:
