Module development and code questions

Hello,

Hello,

I am creating a module. But when I go to the module's page (/mymodule), I get the following error:

Access denied

You are not authorized to access this page.

These are the files of my module:

mymodule.info.yml:

name: My First Custom Module
type: module
core_version_requirement: ^9
description: 'My first Drupal module'

Hi, 

I have Drupal 9.2.6 in the intranet site, and I am using Bootstrap Paragraph, specifically Accordion Section.  I would love to have Bootstrap Collapsible Panel With Up/Down Arrow Icon on the Accordion Section to show the up/down arrow under Drupal. Is there a way to set up an icon in the Accordion Section ?  Or do I have to write a HTML code to make it happen ?

Thank you.

Hi bit of a newbie here.
I used the page module to create a page using URL /someurl and then deleted the page. I created another page (yes - I should of used variants) with the same URL /someurl and now I get the page cannot be found.

I refreshed - check the DB (don't want to even think of touching this)

Is there a "simple" explanation?

I'm converting my Drupal 7 app to Drupal 9. I had used some fancy Ajax techniques to dynamically alter some form elements. I'm having a hard time figuring out the subtleties of Drupal 9. Nothing is happening with what I'm doing so far. No errors either.

 I want to dynamically set the list of offices for a selected district.

It is not clear to me when to use ['widget'][0]['value']['#ajax'] and ['widget']['#ajax']. And recently I've seen 'target_id' in other posts about this sort of thing.

I have installed smart date, Smart Date Starter kit, smart date recur, etc

https://www.drupal.org/project/smart_date

I have this working in views and it is showing event recurring dates fine, but when I try to call the date from the event twig.

It is working in the views but when I try to call it in events twig, nothing is showing.

{{ content.field_MY_EVENT_FIELD_DATE }}

{{ node:field_MY_EVENT_FIELD_DATE.value }}

{{ node.event.field_MY_EVENT_FIELD_DATE }}
