voting_only node return number_format_exception error

[bandrea83]

When you try to read prometheus metrics from a voting_only node it return current error:

{"error":{"root_cause":[{"type":"number_format_exception","reason":"For input string: "max""}],"type":"number_format_exception","reason":"For input string: "max""},"status":400}

i think it must be managed

[mindw]

@bandrea83 can you please attach relevant logs from the above node? a stack trace would be of the greatest help.
Till then there is very little that can be done.
