SchoolProject | School Project with ASP.NET MVC | Model View Controller library

I have a schoolproject where I have to scrape about 88 000 companies in Belgium. Some websites take a bit longer to find a word on the site, so I assume this is just a bigger website. However, when I get to the website of DHL (www.dhl.com), my program does not do anything. Is there a reason this is not possible or can a company disable scraping their website? I do not think there is anything wrong in my code, but I've placed it below. The variable websites is just an array with all the URL's of the companies.

i'm trying to export a component using export default project; and importing using

import project, {toggleCattegories} from './project';

i get the following warning:

I am having some issues with DigitalOcean A records and CNAMEs. An A record for www.schoolproject.me was created, and DO would not let me make one for just schoolproject.me (do I need to make one for @.schoolproject.me instead?).

When checking both of those domain names for A records on either MXToolbox or a propagation checker, neither of them provide any response whatsoever. For subdomains of this, I have CNAMEs done in DO as well (this is an Evilginx project, so ones for api.twitter.com.schoolproject.me, abs.twitter.com.schoolproject.me, and twitter.com.schoolproject.me) which also don't have CNAMEs in MXToolbox.

The nameservers were set up in Namecheap, as nsX.schoolproject.me - 1-3 as X that point to the IP of the DO droplet, as suggested in Evilginx setup guides.

The question is, why aren't these A records and CNAMEs showing up in any tool? When Evilginx attempts to get SSL certs from LetsEncrypt I am met with this -

I have to use a class as a database for a winforms project in c# for a schoolproject but we haven't learned mySQL yet as. How do i use a class as a database without mySQL?

for a schoolproject we have to make a webshop in elixir that can create new products by uploading a csv file. We tried implementing this by following How to import users from csv file with elixir/phoenix? but we always get an error (see title)
Can anybody help us out? Here is our code:

I'm trying to build an weatherapplication for a schoolproject in React. I've gotten so far that when i search for London, it will show me the current temprature and other useful information i've chosen to display. I simply want a message to appear that the city could not be found, i guess this somehow should done in a variable and with help of If statements?

However im not sure how i handle if the user types something that that isnt there, for example "new jorc" instead of New York. My current code looks like this.

I'm trying to get the current location of the user of the app every 2 seconds.

I already use a foreground service with notification (can record location when app is in background). But when the app enters doze mode it will continue to give 3 locations after the screen turns black. But will then stop giving me locations updates.

I'm using FusedLocationProviderClient to get my current location. I have a WakeLock to keep the service running and this works. To test this I have a corourtine running and I can do println("test") but when i want my location i get nothing.

I have a problem with my AutoML code. I want to link it to a web project. I've used the Google tutorial but it doesn't work. I receive this error in my console :

Using Keras, I am trying to loop a training session 10 times with different splits of data. Though, after every loop my accuracy increases a lot probably because it doesn't reset and sees new data in new groups (data trained on might appear in test next loop)

I expected model.fit to reset it over, as pr. an answer here saying it does so but I can't get it to. I then tried K.clear_session() in the start of the loop, as pr. example 1 here, but it does nothing. I can save an untrained model the first time and reload it at start of loop, but this seems like a bad method/bad practice. What can I do instead/am I doing wrong?
