"Could not resolve path error" in the jsonparse section in job run for Chainlink external adapter

I have a job for an external adapter added to my local Chainlink node. It errors out when I make an initial request. My problem comes down to a syntax error or using the incorrect path. But I'm not aware of where to find out what the syntax should be. Or am I getting the path wrong?

Below is my job definition.

type = "directrequest"
schemaVersion = 1
name = "f1latestresults"
contractAddress = "0x765aCc258f3a7b2D8d103D1A9310fc51b07D5425"
maxTaskDuration = "0s"

                  data="$(jobRun.logData)"
                  topics="$(jobRun.logTopics)"]

Can you try remove the square brackets and use commas. ie instead of

Races[0]

Try

Races,0

ie:

data,MRData,RaceTable,Races,0,Results,0,number

If that doesn't work, please post your entire JSON output
