drush pm-update

After update it gives below error

Fatal error: Class 'Aws\S3\StreamWrapper' not found in //web/modules/contrib/s3fs/src/StreamWrapper/S3fsStream.php on line 23

Any idea how to fix this?

Hi,
I'm creating a site on Drupal for the first time
I'm using Layout Builder to display news. I add a title block, but it displays as span:
<div class = "content">
       <span class = "field field - name-title field - type-string field - label-visually_hidden"> Title 1 </span>
     </ div>

how to change it to h1?

Thank you.
ps. sorry for my English

I just went through a lengthy process of updating Drupal 8.7.10 to a Composer-managed 8.8.x setup using this helpful guide. It was successful, but I failed to realize that those instructions installed a dev version of 8.8.x (I assume it was written before 8.8.x was stable). I used the following code (from the guide linked above) to install Drupal 8.8.x:

I'm a total Drupal newb. :D
I have a fresh install of Lightning Drupal 8.8.1

I'm looking through the list of modules, to learn what is installed and what I might want to enable.

I cannot find any info about the module: Simple OAuth Extras
Machine name: simple_oauth_extras

If anyone has a link to the module info page, that would be great.

Is it common to get modules installed by Distirubions that have no info on the Drupal web site?

I have a blog view which I want to override. I am using node twig to do this. But the problem I am facing is the format to be used to get the values. I understand that to get the title or body, we use this - {{ content }} {{ content.body }}. But I want to get the values of the tags in the blog article, authored by, authored on, the image/picture of the author. What is the code to get these values? 

In the view, I have set Format: Unformatted List and Show: Content, Teaser.

Hello,

I have a question. I would appreciate your answer.

How should I provide data to my service correctly? For example in submitForm:

$this->session->set('var1', $name);
$this->session->set('var2', $count);
$form_state->setRedirect('test.task');

Then I have service where I want access the data from session and save in database. Should I read data from session in controller and pass to service by parameter? I guess no but I don't have any other idea. Regards :)
