Hi there,
I am trying to build a function (in Julia) on top of some of the functions found in this JSON RPC documentation.
function eth_getBlockByNumber(block_number, boolean_value)
#block_number: pass as Int
#boolean_value: true or false (If true, returns full tx objects; if false, only hashes of tx)
block_number = string(block_number, base=16) #convert to hex for JSON
block_number = "0x" * block_number
uri = "http://localhost:8545/"
header = ["Content-Type"=> "application/json"]
data = """{"jsonrpc":"2.0","method":"eth_getBlockByNumber","params":[$block_number, $boolean_value],"id":1}"""
r = HTTP.request("POST", uri, header, data)
result = JSON.parse(String(r.body))
return result
end
Which when I run with a block number argument, returns this error:
"error" => Dict{String,Any}("message"=>"invalid character 'x' after array element","code"=>-32600)
And if I run it without the "0x" added, I get the same error, just that the invalid character is the first character in the block_number string, whatever it may be. I've looked at the HEX value encoding section, but am not sure where I am going wrong.

Thanks for any help.
