Getting this error when trying to run the script:

getting below and nothing is happening after that:
$ npm i

I saw your config file[https://github.com/theoomoregbee/US-visa-appointment-notifier/blob/main/.env.example] line-15 asking for MAILGUN_DOMAIN='mailgun domain' but I dont know what value i put it there from the below mailgun info I have...

My mailgun account gave me the following:

`curl -s --user 'api:b84a-72f'
https://api.mailgun.net/v3/sandbox37****************22.mailgun.org/messages
-F from='Mailgun Sandbox <postmaster@sandbox37**22.mailgun.org>'
-F to='Sam **@outlook.com'
-F subject='Hello Sam'
-F text='Congratulations Sam, you just sent an email with Mailgun! You are truly awesome!'

Your guidance will be appreciated. Thank you in advance

I'm getting the below error while the app sends out an email. I have used the same parameter and key values using postman and it worked.

          how we can run this code for any other country to setup the email alert for the appointment? Thanks

When the code reaches the sending email part, I get this error: [Error: Not Found] { status: 404, details: '404 page not found\n' }. I think this is either the mailgun domain or the API key, I'm taking both from mailgun control panel>sending>overview "API-key" and "API base URL" fields

I think the API link: https://ais.usvisa-info.com/en-ca/niv/schedule/{SCHEDULEID}/appointment/days/Toronto.json?appointments%5Bexpedite%5D=false, doesn't work anymore.

Can you do the proxy settings for this script? I searched for Puppeteer but it always gave an error.

How do I find my own facility id?

I added the authorized recipient e-mail address and got it approved, but it still gave the same error.

There is no api that starts with key--xxxx

the one i could find under the sandbox domain does not seem to work.

Can you please help to identify which api key to use?

Email should be sent only once .. index.js need an else at line 92

Your code works great, but after few api calls (like 100 or so) api start sending empty list. I believe there this rate limiter per account on https://ais.usvisa-info.com/en-ca/, any idea how can we over come that?

A wonderful tool! But I'm not sure if I can set the NEXT_SCHEDULE_POLL to a small number, like 1 min, because I'm a little concerned that my account will be locked if the query frequency is high. Does anyone know that?

And can I add two ids in the FACILITY_ID field?

I am trying to run this on my Mac.

1. I saved the folder on Desktop
2. I try to run the code on terminal but it isn't working

Could you please help me with the full syntax of what to type in Terminal to run this script from scratch?

I have added the values to config.js and saved it as config.env.
I have created an account on Mailgun, got the API key, and I've added authorized recipient.

Hoping to hear from you. These could come across as dumb questions, apologies for that. Thanks.

Hi, thanks for your work

Right now I getting "[]" after the "Step: checking for schedules"

Any idea why?

Getting "TypeError: Cannot read properties of null (reading '$')" when running npm start, Kindly help

Hello

Program is working well but the emails arent going through to my email and its the same as my mailgun username

for eg-Available date- [{"date":"2026-06-10","business_day":true}

in my config - NOTIFY_ON_DATE_BEFORE: 2026-11-11,

NOTIFY_EMAILS: '[email protected]',
mailgun: {
USERNAME: '[email protected]',
DOMAIN: 'sandboxfddxxxxx.mailgun.org',
API_KEY: 'pubkey-xxxx-xx-xx',

How can I control 2 facilities at the same time?

This error appear and corresponds to the line where it's written const email = await form.$('input[name="user[email]"]');

Hello,

I can see so many restrictions on the portal is this still valid ?

Hi,

First, thanks a lot for the repo. It is indeed still working and quite simple to setup/modify.

I am curious what search rate is recommended to use? I often notice that while I have the script running, the website shows "no available appointments" when checked through the browser and I wonder if it is some sort of a DDoS protection mechanism that simply shuts down on rate querying?

Hello. I haven't scheduled a date so far as all the calendar dates are unavailable. Can the script used to notify me whenever any dates become available?

After it runs the script and logs in it gives this prompt :
at login (D:\US-visa-appointment-notifier-main\index.js:17:28) at process.processTicksAndRejections (node:internal/process/task_queues:95:5) at async process (D:\US-visa-appointment-notifier-main\index.js:85:19) at async D:\US-visa-appointment-notifier-main\index.js:103:5

hi there, Im getting the below error, do i need to login somewhere before i run this script, there are my cred saved in the .env.

**> [email protected] start

=====>>> Step: logging in

The script shows dates that are not open.For example, the closest date is 06.25.2025 but the script shows 05.21.2024.The dates I checked are not open.

Hi, i am trying to run the project but i cant find my shcedule id in the visa website. Where i can find it?

Thank you.
