This is my first time posting in this plateform so if my request lacks informations let me know so I can provide them.
I'm trying to run my end to end tests using Webdriver IO, I've been running my tests locally at first but now I need to execute them in a Gitlab CI pipeline using a docker image, and here are some information about the setup:
Docker image:
it's an alpinedocker image
node version: 12.18.3
npm version:6.14.6
Java version: openjdk "11.0.8"
Chromium: 85.0.4183.83
Mozilla: 80.0.1
Webdriver IO configuration:
latest versions of webdriver IO framework, geckodriver, and wdio-geckodriver-service
Here is my wdio.cong.js file
const { generate } = require('multiple-cucumber-html-reporter');
const { removeSync } = require('fs-extra');
exports.config = {
runner: 'local',

}
}
],

requireModule: [

require('ts-node').register({ files: true, project: './tsconfig.json' });
}
],
require: ['./**/**/*.step.ts']
},
onPrepare: function(config, capabilities) {
removeSync('./cucumberjs-reports');
},
onComplete: function(exitCode, config, capabilities, results) {
generate({
jsonDir: './cucumberjs-reports/json',
reportPath: './cucumberjs-reports/report'
});
}
};
My package.json:

I am just trying to start a supervisor with only one child that gets a parameter in its init method. What is wrong in this code?
The second argument of start_link with 3 arguments is supposed to be the module name; it should be
start()->
supervisor:start_link({local,?MODULE}, ?MODULE, [#state{data=[0|1]}]).
When I try to start the deployed app, I get this error:

It would be really helpful, if someone can point what am doing incorrectly.
The message says that in the line Mnum1 = MAX + Counternum rem ( 2 - 1 ), you are trying to add error with 0 (by the way Counternum rem ( 2 - 1 ) is always equal to 0 so there must be an error here).
Max is the result of {MAX, _} = string:to_integer(Maxstr),, it is equal to error if Maxstr is not a string starting by an integer:
"123" will return {123,[]}
"123 ab" will return {123," ab"}
"a123" will return {error,no_integer}
an_atom will return {error,not_a_list}
To debug further verify the value of Maxfound and Maxstr
you can also shorten your code using the function io:fread/2 which will directly return an integer.
My Erlang applicaation processed crashed and then exited, but found that the erlang VM is still running.
I could recieve pong when ping this "suspended node"
Types regs() and the results show below, there is not my app process.
