Module development and code questions

Hi Folks

I am starting to try and use the drupal graphql module and have been following a tutorial here

I am using version 4 and I assume this tutorial is v3 but can anyone explain to me how i can return all nodes of type product

below returns a single node 

query {
product(id: 3) {
id
title
image
price
}
}

Hello everyone, I have been trying to find why when creating a taxonomy from a controller in submit of webform module it stays in that process and does not respond until the timeout expires, but if it creates the taxonomy without a problem, as if after creating it it stays in an internal loop

I've searched here and in the modules and I was wondering what would be the best practice to achieve the following:  we have a  multisite installation of drupal 9 with different subdomains based on clients persona.  I'm setting a cookie to remember anonymous visitors choice's of persona and redirect to the appropriate subdomain.  I can see a couples of ways to do it but i'm curious to read about your's.

Thanks a lot,     

Hi, So I bought a Restaurant theme and I am trying to add it and before I was getting POST 8888888 bytes exceeds limits so I made a change in the php file(running xampp) and Now I get this error The file could not be saved because it exceeds 2 MB, the maximum allowed size for uploads. Any suggestions on what code to add? Im new to Drupal and I really dont know php at all. Thanks in advance!

I have a scenario where i have built a customer a D9 Commerce webshop abc.com . The customer also has bought another exisiting webshop/domain def.com which they will close down but keep the domain.

What they want to do is 301 redirect from def.com to abc.com but anyone using this redirect will see the logo from def.com rather than the new logo on abc.com.

I don't think it can be done. Any ideas?
