The three columns in the table corresponds to the three fields
in the JSON-RPC error object. The code
field is intended to be machine-readable.
The message field is a human-readable string intended
for display to a user or for inclusion in a log file.
The data field contains the values of the positional
parameters from the message string in case that the
client wishes to customize the error message.
