Briefly, this error occurs when Elasticsearch is unable to find a configured port for a specific profile, hence it cannot bind to it. This could be due to incorrect configuration settings or missing port details. To resolve this issue, you can: 1) Check your Elasticsearch configuration file (elasticsearch.yml) to ensure that the correct port is specified for the profile. 2) If the port is in use by another service, change the port number to an unused one. 3) Ensure that Elasticsearch has the necessary permissions to bind to the specified port.

                                .put("port"; profileSettings.get("port"; this.settings.get("transport.tcp.port"; DEFAULT_PORT_RANGE)))
                                .build();
                    } else if (profileSettings.get("port") == null) {
                        // if profile does not have a port; skip it
                        logger.info("No port configured for profile [{}]; not binding"; name);
                        continue;
                    }

                    // merge fallback settings with default settings with profile settings so we have complete settings with default values
                    Settings mergedSettings = settingsBuilder()
