Error in starting tb-js-executor:3.3.3

In starting tb-js-executor:3.3.3 the following error is recorded:

2022-02-18 10:48:02,925 [main] INFO: kafka template started.
2022-02-18 10:48:03,725 [main] ERROR: uncaughtException: options.port should be >= 0 and < 65536. Received NaN.

It seems the offending line is:

(/usr/share/tb-js-executor/api/httpServer.js:30:5)

where it tries to start a web server for readiness probe:

app.listen(httpPort, () => logger.info(Started http endpoint on port ${httpPort}. Please, use /livenessProbe !))

using the httpPort config parameter:

const config = require('config'),
logger = require('../config/logger')._logger('httpServer'),
express = require('express');

const httpPort = Number(config.get('http_port'));

But it seems the config parameter httpPort cannot be retrieved.

Indeed, looking at the source, the config file is in config/default.yml

http_port: "8888" # /livenessProbe

but it seems it cannot be read or its type is not correct, so ending up in the error:

port should be >= 0 and < 65536. Received NaN.

Thanks
