Module development and code questions

Context:
Drupal 9.5 sites (preparing to upgrade) and php 7.4
The local development environment setup with  ddev. 
Two branches: main and develop. 
Locally I use drush and composer.
I dont have drush and composer on the server.
So locally I use drush config:export and config:import to export and merge.
On the server I use the UI to import the configurations.

Hey Guys! I would like to share that there is an issue with my Drupal portal (connected with Apigee). This issue just happened few days ago and for some reason Apigee Connection stops working. I am still using the same connection file that I used to use so I don't know what has changed in the Login module or so on.

Greetings everyone,

I am using the 'date_recur' module and trying to get a list of nodes with the last end date of occurrences using \Drupal::entityQuery.

I have a form (Form1) in my installation profile. This form retrieves an object using a json request. Now I need to persist the entire object class in session so I can access it from Form2

I do
\Drupal::request()->getSession()->set('obj_var', $object)
in Form1.

I am not sure where to post this, if there is a better place this question fits let me know. But I am a student website developer for my university. We have this website here: https://signetwork.org/

In 2010 I created a free portal (marketingaziende.it) in which each company with a VAT number could create its own web page for advertising and marketing. Initially, the page was very simple and the html necessary for the visualization of the company was inserted in the body field of the node (type 'story').
