Checking validators missed blocks

[aner87]

Hello,
first of all, amazing project, congrats! :)

Secondly, I'm playing around with the documentation and I'm trying to make some queries via NodeJS...
So far I used with satisfaction many of the queries that are reported here on GitHub, but then I wanted to go deeper and tried some that are not documented in the repo, yet.

Only problem, I just can't figure out how to use the two functions to retrieve data about validators' missed blocks:
"sessionTotalMissedBlocksCount" and "MissedOfPerSession".
Every argument I pass into these 2 funcs exits with result 0...which is obviously not true by consulting https://scan.chainx.org/validators/missed

What am I missing? Am I using the wrong functions?
Can somebody explain to me how they are supposed to be used?
Thanks, appreciated!

hi, this is a sample

const Chainx = require('chainx.js').default;

(async () => {
  const chainx = new Chainx('wss://w1.chainx.org/ws');

  await chainx.isRpcReady();

  chainx.api.query.xStaking.offlineValidatorsPerSession
    .at('0x0665d93ea70447a9597caff3f189e56b5e05c7c8ff35622b4887b0807aaf3d83')
    .then(res => {
      console.log('offlineValidatorsPerSession: ' + res);
    })
    .catch(err => {
      console.log(err);
    });

  chainx.api.query.xStaking.missedOfPerSession
    .at(
      '0x0665d93ea70447a9597caff3f189e56b5e05c7c8ff35622b4887b0807aaf3d83',
      '5QccQsc53KdTnBmaB5HkTZwYyQQj9bcwVLPWqn1DZzgQNdux'
    )
    .then(res => {
      console.log('missedOfPerSession: ' + res);
    })
    .catch(err => {
      console.log(err);
    });
})();
